Environment-Friendly Cottonseed Protein Bioplastics: Preparation and Properties

Article Preview

Abstract:

A novel class of environmentally friendly protein-based bioplastics—cottonseed protein plastic sheets (CP-sheets)—were prepared by compression molding in the presence of cottonseed flour as main raw material, aldehydes as crosslink agent and glycerol as plasticizer. FTIR, TGA, tensile tests and water uptake measurements were applied to characterize the structure, thermal stability, mechanical properties and water absorption of the CP-sheets. It was found that the crosslinked CP-sheets (CP-FA, CP-GX and CP-GA) showed higher thermal stability and tensile properties, less water uptake than the CP-sheet withou crosslinking treatment (CP-0CL). The CP-sheets with good thermal, mechanical and hydrophobic properties are emerging and promising bioplastics for potential applications in food packaging as well as flower planting.
