Corn Stalk Filled Low Density Polyethylene Bio Composites: Influence Maleic Anhydride Grafted Polyetylene

摘要

The effect of corn stalk content and compatibilizer on tensile properties and morphology of Low Density Polyethylene (LDPE)/Corn Stalk (CS) biocomposites was studied. The results found that the tensile strength and elongation at break decreased, but Young's modulus increased with increasing CS content. The dispersion and interfacial adhesion between the CS filler and thermoplastic were important factors affecting the tensile properties of composites system. In order to improve the compatibility and interfacial adhesion, maleic anhydride polyethylene (MAPE) as compatibilizer was added into LDPE/CS biocomposites. The addition of MAPE has enhanced tensile properties and interfacial interaction between CS and LDPE biocomposites, as demonstrated in SEM study.
