▎ 摘  要

NOVELTY - A graphene-degradable resin masterbatch is prepared by preparing two N,N-dimethylformamide solutions, ultrasonically dispersing 1:5-1:10 mass ratio of 1-10 g graphene and 10-100g chain extender in 1L N,N-dimethylformamide solution, respectively, adding graphene-containing N,N-dimethylformamide solution to chain extender-containing N,N-dimethylformamide solution, stirring, filtering, freeze drying, obtaining modified graphene, mixing 0.5-5 wt.% modified graphene with 0.5-5 wt.% antioxidant and 0.5-2 wt.% degradable resin particles, stirring, melt extruding, water cooling, and granulating. USE - Method for preparing graphene-degradable resin masterbatch for preparing degradable film material (involves).
