Novel One-Step Process for the Production of Bioplastic from Rapeseed Press Cake

Crude rapeseed cake was employed as the starting material for preparation of protein-based bioplastic films through a wet process. A simple exposure agricultural waste to formic acid realized at 40 °C 15 min could afford slurry ready producing robust by casting without another plasticizer addition. After determining optimal process conditions, all and membranes were successively characterized DSC FT-IR spectroscopy. They also tested their water absorption capacity, tensile strength, elongation break performance. The respective surface morphology elementary composition products determined FE-SEM/EDX. Some attempts improve intrinsic properties performed loading graphene oxide inside biopolymer three-dimensional matrix.
