| الوصف: | International audience ; Polyhydroxyalkanoates (PHAs) are thermoplastic polyesters produced as carbon and energy storage compounds by microorganisms under nutritional stress. Short-chain-length PHAs, mainly represented by poly(3-hydroxybutyrate) P(3HB) and the copolymer poly(3-hydroxybutyrateco-3-hydroxyvalerate)P(3HB-co-3HV) are already commercially available. PHBV can be produced using carbon sources from waste or byproducts of agriculture and food industries. This would further promote circular economy because local food waste could be used to make food containers. PHBV is a stiff, brittle, highly crystalline polymer with low thermal stability and a narrow processing window. One strategy that can be adopted to overcome these drawbacks is based on physical melt-blending. In-situ compatibilization can be used to improve the mechanical properties thanks to the enhancement of interfacial adhesion between both phases in binary blends. We developed PHBV/PBSA blends compatibilized with dicumyl peroxide (DCP) and investigated the morphological rheological, thermal, mechanical characteristics, and processability. The formulation, optimized using melt blending, could be processed using film-blowing extrusion. Blown films were then tested in a service situation, corresponding to frozen food packaging. |
