▎ 摘 要
NOVELTY - The preparation method of low temperature graphene reinforced toughened epoxy resin composite material involves introducing multi-amine compound into graphene surface through dopamine-modified graphene using amino-dopamine Schiff alkali or Michael addition reaction to obtain modified graphene, and solidifying modified graphene and epoxy resin. USE - Preparation of low temperature graphene reinforced toughened epoxy resin composite material (claimed). ADVANTAGE - The method enables preparation of low temperature graphene reinforced toughened epoxy resin composite material with excellent strength and toughness, and improved dispersion of graphene in epoxy resin.
