Abstract: A biodegradable material was prepared by blending corn starch with polyvinyl alcohol (PVA), water, and glycol. With 25phr of PVA and 30 phr of water, the tensile behavior underwent a brittle-ductile transition, the tensile strength and elongation at break increased from 25.80MPa and 1.11% for neat corn starch to 31.78MPa and 6.24%. When borax and glycol were added, the tensile strength and elongation at break were further increased to 36.26MPa and 11.71%, respectively.
Key words: corn starch, poly (vinyl alcohol), biodegradable material
