description Publicationkeyboard_double_arrow_right Article , Other literature type 2024 ItalyPublisher:MDPI AG Authors: Oleandro E.; Stanzione M.; Buonocore G. G.; Lavorgna M.;Nanomaterials, due to their unique structural and functional features, are widely investigated for potential applications in a wide range of industrial sectors. In this context, protein-based nanoparticles, given proteins’ abundance, non-toxicity, and stability, offer a promising and sustainable methodology for encapsulation and protection, and can be used in engineered nanocarriers that are capable of releasing active compounds on demand. Zein is a plant-based protein extracted from corn, and it is biocompatible, biodegradable, and amphiphilic. Several approaches and technologies are currently involved in zein-based nanoparticle preparation, such as antisolvent precipitation, spray drying, supercritical processes, coacervation, and emulsion procedures. Thanks to their peculiar characteristics, zein-based nanoparticles are widely used as nanocarriers of active compounds in targeted application fields such as drug delivery, bioimaging, or soft tissue engineering, as reported by others. The main goal of this review is to investigate the use of zein-based nanocarriers for different advanced applications including food/food packaging, cosmetics, and agriculture, which are attracting researchers’ efforts, and to exploit the future potential development of zein NPs in the field of cultural heritage, which is still relatively unexplored. Moreover, the presented overview focuses on several preparation methods (i.e., antisolvent processes, spry drying), correlating the different analyzed methodologies to NPs’ structural and functional properties and their capability to act as carriers of bioactive compounds, both to preserve their activity and to tune their release in specific working conditions.

In the last decades, bio-derived natural materials, such as vegetable oils, polysaccharides and biomass represent a rich source of hydroxyl precursors for the synthesis of polyols which can be potentially used to synthesize "greener" polyurethane foams. Herein a bio-based precursor (obtained from succinic acid) was used as a partial replacement of conventional polyol to synthesize PU foams. A mixture of conventional and bio-based polyol in presence of catalysts, silicone surfactant and diphenylmethane di-isocyanate (MDI) was expanded in a mold and cured for two hours at room temperature. Experimental results highlighted the suitability of this bio-precursor to be used in the production of flexible PU foams. Furthermore the chemo-physical characterization of the resulting foams show an interesting improvement in thermal stability and elastic modulus with respect to the PU foams produced with conventional polyol.

Waste polymeric material, classified as secondary raw material, mainly consisting of selected polyolefins, PE and PP, and PET has brought great pressure on the environment, due to the large quantities produced by the urban lifestyles and economic activity. This research evaluated the possibility to reuse the plastic waste as aggregates in hydraulic lime based composite mortars.The composite mortars were prepared by replacing the conventional aggregate, silica sand, with 10, 15, and 20 % of fiber polymeric waste in a mixture of lime and water. The chemico‐physical interaction between the recycled plastic aggregates and the lime matrix was examined through FTIR, X‐Ray diffraction and morphological analyses. The effect of fiber polymeric waste on the degree of hydration and mechanical performances of the produced composites was also evaluated. Experimental results show that the good chemical interaction between the fiber plastic aggregates and the mortar induced an improvement of ductility of mortar composites. However, the plastic waste limited the degree of hydration of the hydraulic lime, due to the organic characterof the plastic as opposed to the inorganic character of lime. © 2014 American Institute of Chemical Engineers Environ Prog, 33: 1445–1451, 2014

AbstractThe incorporation of siloxane networks in sulfonated polystyrene membranes by the sol‐gel process was used to explore the possibility of developing low cost membrane for direct methanol fuel cells. A precursor solution of a hydrophobic siloxane network was allowed to diffuse and react into sulfonated syndio‐polystyrene ionomeric membranes. The organic‐inorganic hybrid domains so produced were able to reduce considerably the swelling of the ionomeric polymer in water, thereby increasing the dimensional stability of membranes. The physical and chemical properties of the sulfonated and hybrids membranes were examined by thermogravimetric analysis (TGA), infrared spectroscopy (FTIR) and small angle X‐ray scattering (SAXS) analysis. The water uptake and the ionic conductivity were also evaluated at temperatures up to 60° C. It was found that both the unmodified sulfonated membranes and the corresponding hybrid exhibited a two‐phase morphology, consisting of crystalline lamellar domains embedded in the amorphous ionomeric polymer, featuring segregated hydrophobic/hydrophilic domains with characteristic separation lengths ranging between 3.9 and 1.7 nm. The presence of inorganic domains not only increased the dimensional stability of the membrane, by reducing the water uptake, but also decreased the rate of methanol crossover. Furthermore it was found that the inorganic network stabilizes the membrane morphology, enhancing the retention of proton conductivity after aging in water. POLYM. ENG.

AbstractRecently, more and more attention has been focused on new techniques for energy production also in view of environmental problems. A noticeable device is small fuel cell that converts chemical energy into electric energy by electrochemical reaction of hydrogen with oxygen, and exhibits a high‐energy efficiency. Conventional small fuel cells have been classified into phosphoric acid‐type fuel cells, molten carbonate‐type fuel cells, solid oxide‐type fuel cells, solid polymer type fuel cells, etc., according to the type of electrolyte used. The target of this work is the development of a new process to build up polyelectrolyte membranes, for polymer type fuel cell (PEM), by sulfonating syndiotactic polystyrene in its clathrate form. The polyelectrolyte membranes of this paper are inexpensive and exhibit good long‐term stability and ion exchange capability.

Aminolysis is widely recognized as a valuable chemical route for depolymerizing polymeric materials containing ester, amide, or urethane functional groups, including polyurethane foams. Bio-based polyurethane foams, pristine and reinforced with 40 wt% of sustainable fillers, were depolymerized in the presence of bio-derived butane-1,4-diamine, BDA. A process comparison was made using fossil-derived ethane-1,2-diamine, EDA, by varying amine/polyurethane ratio (F/A, 1:1 and 1:0.6). The obtained depolymerized systems were analyzed by FTIR and NMR characterizations to understand the effect of both diamines on the degradation pathway. The use of bio-based BDA seemed to be more effective with respect to conventional EDA, owing to its stronger basicity (and thus higher nucleophilicity), corresponding to faster depolymerization rates. BDA-based depolymerized systems were then employed to prepare second-generation bio-based composite polyurethane foams by partial replacement of isocyanate components (20 wt%). The morphological, mechanical, and thermal conductivity properties of the second-generation polyurethane foams were evaluated. The best performances (σ10 %=71 ± 9 kPa, λ = 0.042 ± 0.015 W∙ m-1 ∙K-1) were attained by employing the lowest F/A ratio (1:0.6); this demonstrates their potential application in different sectors such as packaging or construction, fulfilling the paradigm of the circular economy.

Verdolotti; V. Russo; P. Campaner; A. Minigher; G. C. Lama; L. Boggioni; R. Tesser; M. Lavorgna;It is well known that the traditional synthetic polymers, such as Polyurethane foams, require raw materials that are not fully sustainable and are based on oil-feedstocks. For this reason, renewable resources such as biomass, polysaccharides and proteins are still recognized as one of the most promising approaches for substituting oil-based raw materials (mainly polyols). However, polyurethanes from renewable sources exhibit poor physical and functional performances. For this reason, the best technological solution is the production of polyurethane materials obtained through a partial replacement of the oil-based polyurethane precursors. This approach enables a good balance between the need to improve the sustainability of the polymer and the need to achieve suitable performances, to fulfill the technological requirements for specific applications. In this paper, a succinic-based polyol sample (obtained from biomass source) was synthesized, characterized and blended with cardanol-based polyol (Mannich-based polyol) to produce sustainable rigid polyurethane foams in which the oil-based polyol is totally replaced. A suitable amount of catalysts and surfactant, water as blowing reagent and poly-methylene diphenyl di-isocyanate as isocyanate source were used for the polyurethane synthesis. The resulting foams were characterized by means of infrared spectroscopy (FTIR) to control the cross-linking reactions, scanning electron microscopy (SEM) to evaluate the morphological structure and thermal gravimetric analysis (TGA) and thermal conductivity to evaluate thermal degradation behavior and thermal insulation properties.

Polysiloxane-modified hybrid membranes were prepared by introducing in a pre-swelled commercial Nation membrane a sol-gel precursor solution, consisting of a pre-hydrolyzed mixture of tetraethoxysilane and a mercaptan functionalized organoalkoxysilane. The structure of the polysiloxane network was changed by altering the ratio of the two silane components within the precursor solution. The mercaptosilane modifier was used to provide an additional source of acidic Bronsted sites through the oxidisation of the mercaptan groups to sulforric acid groups. The physical and chemical properties of the hybrid membranes were examined by TGA, FT-IR and SEM-EDS analysis. The water vapor sorption and proton conductivity characteristics were evaluated at 40, 60 and 70 degrees C and with water activity in the region of 0.4-1. It was found that the polysiloxane network alters the water vapor sorption mechanism of the Nafion membrane, resulting in an increase in the equilibrium amount of water absorbed in the middle range of water activity (0.4-0.6). At the same time, the increased water sorption capability produced a concomitant increase in ionic conductivity at low water activities

In the last decades, bio-derived natural materials, such as vegetable oils, polysaccharides and biomass represent a rich source of hydroxyl precursors for the synthesis of polyols which can be potentially used to synthesize "greener" polyurethane foams. Herein a bio-based precursor (obtained from succinic acid) was used as a partial replacement of conventional polyol to synthesize PU foams. A mixture of conventional and bio-based polyol in presence of catalysts, silicone surfactant and diphenylmethane di-isocyanate (MDI) was expanded in a mold and cured for two hours at room temperature. Experimental results highlighted the suitability of this bio-precursor to be used in the production of flexible PU foams. Furthermore the chemo-physical characterization of the resulting foams show an interesting improvement in thermal stability and elastic modulus with respect to the PU foams produced with conventional polyol.

Waste polymeric material, classified as secondary raw material, mainly consisting of selected polyolefins, PE and PP, and PET has brought great pressure on the environment, due to the large quantities produced by the urban lifestyles and economic activity. This research evaluated the possibility to reuse the plastic waste as aggregates in hydraulic lime based composite mortars.The composite mortars were prepared by replacing the conventional aggregate, silica sand, with 10, 15, and 20 % of fiber polymeric waste in a mixture of lime and water. The chemico‐physical interaction between the recycled plastic aggregates and the lime matrix was examined through FTIR, X‐Ray diffraction and morphological analyses. The effect of fiber polymeric waste on the degree of hydration and mechanical performances of the produced composites was also evaluated. Experimental results show that the good chemical interaction between the fiber plastic aggregates and the mortar induced an improvement of ductility of mortar composites. However, the plastic waste limited the degree of hydration of the hydraulic lime, due to the organic characterof the plastic as opposed to the inorganic character of lime. © 2014 American Institute of Chemical Engineers Environ Prog, 33: 1445–1451, 2014

AbstractThe incorporation of siloxane networks in sulfonated polystyrene membranes by the sol‐gel process was used to explore the possibility of developing low cost membrane for direct methanol fuel cells. A precursor solution of a hydrophobic siloxane network was allowed to diffuse and react into sulfonated syndio‐polystyrene ionomeric membranes. The organic‐inorganic hybrid domains so produced were able to reduce considerably the swelling of the ionomeric polymer in water, thereby increasing the dimensional stability of membranes. The physical and chemical properties of the sulfonated and hybrids membranes were examined by thermogravimetric analysis (TGA), infrared spectroscopy (FTIR) and small angle X‐ray scattering (SAXS) analysis. The water uptake and the ionic conductivity were also evaluated at temperatures up to 60° C. It was found that both the unmodified sulfonated membranes and the corresponding hybrid exhibited a two‐phase morphology, consisting of crystalline lamellar domains embedded in the amorphous ionomeric polymer, featuring segregated hydrophobic/hydrophilic domains with characteristic separation lengths ranging between 3.9 and 1.7 nm. The presence of inorganic domains not only increased the dimensional stability of the membrane, by reducing the water uptake, but also decreased the rate of methanol crossover. Furthermore it was found that the inorganic network stabilizes the membrane morphology, enhancing the retention of proton conductivity after aging in water. POLYM. ENG.

AbstractRecently, more and more attention has been focused on new techniques for energy production also in view of environmental problems. A noticeable device is small fuel cell that converts chemical energy into electric energy by electrochemical reaction of hydrogen with oxygen, and exhibits a high‐energy efficiency. Conventional small fuel cells have been classified into phosphoric acid‐type fuel cells, molten carbonate‐type fuel cells, solid oxide‐type fuel cells, solid polymer type fuel cells, etc., according to the type of electrolyte used. The target of this work is the development of a new process to build up polyelectrolyte membranes, for polymer type fuel cell (PEM), by sulfonating syndiotactic polystyrene in its clathrate form. The polyelectrolyte membranes of this paper are inexpensive and exhibit good long‐term stability and ion exchange capability.

Aminolysis is widely recognized as a valuable chemical route for depolymerizing polymeric materials containing ester, amide, or urethane functional groups, including polyurethane foams. Bio-based polyurethane foams, pristine and reinforced with 40 wt% of sustainable fillers, were depolymerized in the presence of bio-derived butane-1,4-diamine, BDA. A process comparison was made using fossil-derived ethane-1,2-diamine, EDA, by varying amine/polyurethane ratio (F/A, 1:1 and 1:0.6). The obtained depolymerized systems were analyzed by FTIR and NMR characterizations to understand the effect of both diamines on the degradation pathway. The use of bio-based BDA seemed to be more effective with respect to conventional EDA, owing to its stronger basicity (and thus higher nucleophilicity), corresponding to faster depolymerization rates. BDA-based depolymerized systems were then employed to prepare second-generation bio-based composite polyurethane foams by partial replacement of isocyanate components (20 wt%). The morphological, mechanical, and thermal conductivity properties of the second-generation polyurethane foams were evaluated. The best performances (σ10 %=71 ± 9 kPa, λ = 0.042 ± 0.015 W∙ m-1 ∙K-1) were attained by employing the lowest F/A ratio (1:0.6); this demonstrates their potential application in different sectors such as packaging or construction, fulfilling the paradigm of the circular economy.

Verdolotti; V. Russo; P. Campaner; A. Minigher; G. C. Lama; L. Boggioni; R. Tesser; M. Lavorgna;It is well known that the traditional synthetic polymers, such as Polyurethane foams, require raw materials that are not fully sustainable and are based on oil-feedstocks. For this reason, renewable resources such as biomass, polysaccharides and proteins are still recognized as one of the most promising approaches for substituting oil-based raw materials (mainly polyols). However, polyurethanes from renewable sources exhibit poor physical and functional performances. For this reason, the best technological solution is the production of polyurethane materials obtained through a partial replacement of the oil-based polyurethane precursors. This approach enables a good balance between the need to improve the sustainability of the polymer and the need to achieve suitable performances, to fulfill the technological requirements for specific applications. In this paper, a succinic-based polyol sample (obtained from biomass source) was synthesized, characterized and blended with cardanol-based polyol (Mannich-based polyol) to produce sustainable rigid polyurethane foams in which the oil-based polyol is totally replaced. A suitable amount of catalysts and surfactant, water as blowing reagent and poly-methylene diphenyl di-isocyanate as isocyanate source were used for the polyurethane synthesis. The resulting foams were characterized by means of infrared spectroscopy (FTIR) to control the cross-linking reactions, scanning electron microscopy (SEM) to evaluate the morphological structure and thermal gravimetric analysis (TGA) and thermal conductivity to evaluate thermal degradation behavior and thermal insulation properties.

Polysiloxane-modified hybrid membranes were prepared by introducing in a pre-swelled commercial Nation membrane a sol-gel precursor solution, consisting of a pre-hydrolyzed mixture of tetraethoxysilane and a mercaptan functionalized organoalkoxysilane. The structure of the polysiloxane network was changed by altering the ratio of the two silane components within the precursor solution. The mercaptosilane modifier was used to provide an additional source of acidic Bronsted sites through the oxidisation of the mercaptan groups to sulforric acid groups. The physical and chemical properties of the hybrid membranes were examined by TGA, FT-IR and SEM-EDS analysis. The water vapor sorption and proton conductivity characteristics were evaluated at 40, 60 and 70 degrees C and with water activity in the region of 0.4-1. It was found that the polysiloxane network alters the water vapor sorption mechanism of the Nafion membrane, resulting in an increase in the equilibrium amount of water absorbed in the middle range of water activity (0.4-0.6). At the same time, the increased water sorption capability produced a concomitant increase in ionic conductivity at low water activities
