▎ 摘　　要

NOVELTY - Preparation of perylene anhydride non-covalently modified graphene comprises adding 0.02 g graphene in 80 ml N-methylpyrrolidone, ultrasonically dispersing for 0.5-1 hour, adding 0.0037 g zinc acetate, 0.0392 g 3,4,9,10-perylene tetracarboxylic dianhydride and 0.0242 g tris(hydroxymethyl)aminomethane, continuously ultrasonically dispersing for 0.5-1 hour, reacting under nitrogen atmosphere at 180 degrees C for 10-14 hours, adding the reaction liquid into absolute ethyl alcohol, precipitating, filtering, and vacuum drying the obtained filtrate to obtain purple black product. USE - Preparation of perylene anhydride non-covalently modified graphene used in preparation of epoxy resin-based composite material and high performance shape memory polymer (all claimed). ADVANTAGE - The method is very simple and easy and fully utilizes the synergistic effect of perylene anhydride and graphene.
