▎ 摘　　要

NOVELTY - A graphene modified starch functional composite material comprises 10-80 pts. wt. starch, 0.001-10 pts. wt. graphene, 10-25 pts. wt. plasticizer, 0.5-5 pts. wt. processing additive, 80-10 pts. wt. bio-based polymer material and 0.1-5 pts. wt. functional additive. The plasticizer is purified water, sodium alginate, ethylenediamine, propanetriol, propanediol, ethylene glycol, polyethylene glycol, sorbitol, maltitol, chitosan, chitin, pentaerythritol, 1,4-butylene glycol, tricaprylyl citrate, acetyl tributyl citrate, ethyl acetate, vinyl acetate, glycerin monostearate or toluene sulfonamide. USE - Graphene modified starch functional composite material. ADVANTAGE - The product has complete biological degradability. The method is simple, easy and suitable for industrialization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene modified starch functional composite material comprising taking raw materials, mixing at 45-120 degrees C for 30-45 minutes at rate of 500-3000 revolutions/minute, cooling, melting and plasticizing, extruding, and granulating at 145-190 degrees C.
