▎ 摘　　要

NOVELTY - A degradable polymer nanocomposite material is made of 77-99.4 %mass degradable polymer, 0.1-15 %mass inorganic nanomaterial and 0.5-8 %mass chain extender. USE - Degradable polymer nanocomposite material used for preparing tableware. ADVANTAGE - The nanocomposite material has improved crosslinking, strengthening and toughening effect of nanoparticles, mechanical and thermodynamic properties of biodegradable polymer, thermal stability and reduced processing cost, and is economically prepared by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the nanocomposite material, which involves loading the chain extender on a surface of inorganic nanomaterial, drying, mixing uniformly with degradable polymer, melting and blending at high temperature, reacting and extruding, and molding.
