Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) films were prepared using a cast film technique. Dioxane was chosen over other polymer solvents as it resulted in homogenous with better morphology. Several plasticizers different molecular weights and concentrations added to the biopolymer solution prior casting. Thermal, crystalline, permeability properties analyzed by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray diffraction (XRD), both water vapor...
Abstract The increasing environmental pollution with petroleum‐based plastics has advanced research on biodegradable polymers. Thermoplastic starch (TPS) is one promising candidate due to wide availability from various renewable sources, low cost and biodegradability. However, TPS significant shortcomings, as high water sensitivity mechanical properties. An approach overcome these drawbacks adding nanofillers reinforcement of the matrix. Among nanofillers, montmorillonite clays have...
Abstract This article contributes to the understanding of biobased and biodegradable polyhydroxybutyrate (PHB) bionanocomposites melt processed by pre-industrial methods such as extrusion injection molding reinforced weight contents 1 3 wt% cellulose nanocrystals (CNC) derived from waste streams paper industry. Ultrasonic treatment was used for dispersion CNC, which followed transmission electron microscopy. The thermal properties crystallization behavior were studied thermogravimetric...
Bionanocomposites of poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV) with cellulose nanocrystals (CNC) were processed by extrusion. Differential scanning calorimetry (DSC) showed that increasing the amount CNC overall crystallization time was reduced. Wide angle X – ray scattering (WAXS) diffraction peaks orthorhombic α– type crystalline structure and confirmed nucleating agent effect particles in PHBV matrix. Small X‐ray (SAXS) reducing rate long spacing slower filled sample than PHBV....
Abstract In recent times, the attention of scientific community has been focusing on replacement petroleum-based polymers by others more environmentally friendly. this sense, bionanocomposites based glycerol-plasticized wheat starch and reinforced with cellulose nanocrystals (CNCs) were prepared a solvent-casting process to obtain friendly films. The plasticization was proven be complete in conditions used no residual crystallinity observed any case. incorporation CNCs leads materials...
In this work, new green and fully biodegradable composites, based on corn starch, plasticized with two different amounts of isosorbide filled by poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) microparticles, were obtained melt processing. The analysis their morphologies, crystallinity, structural interactions dynamomechanical properties as well the evaluation moisture resistance biodegradability in soil, performed function plasticizer and/or microparticle amount. morphology,...
Abstract Polyhedral oligomeric silsesquioxanes (POSS ® ) can be added to thermoplastic and thermostable polymers obtain hybrid materials with only a minor tendency suffer ignition. The aim of the work reported was analyse influence an octafunctional POSS in pyrolysis epoxy/amine system as well during combustion process. Thermal degradation modified materials, respect unmodified ones, analysed using thermogravimetric analysis. As content increased stability improved char/ceramic yields were...
