▎ 摘　　要

NOVELTY - Degradable plastic with photo-thermal conversion performance comprises 50-95 pts. wt. degradable polymer material, 2-30 pts. wt. reinforcing agent, and 1-20 pts. wt. graphene modified by hydrophobic association polymer. USE - The degradable plastic with photo-thermal conversion performance is useful in the preparation of thermal insulation film, thermal reactor or crude oil transportation pipeline (claimed). ADVANTAGE - The modify graphene solves the problem graphene and degradable plastics are difficult to mix and process directly, absorbs the degradable plastic near-infrared rays and infrared rays in sunlight and convert them into heat energy, and has broad application prospects in the preparation of thermal insulation film, thermal reactor or crude oil transportation pipeline. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing degradable plastic with photo-thermal conversion performance, comprising (i) dispersing graphene in water, adding hydrophobic association polymer, performing ultrasonic dispersion to obtain graphene modified by hydrophobic association polymer; and (ii) mixing the graphene modified by the hydrophobic association polymer, the reinforcing agent and the degradable polymer material, and using the molding process.
