▎ 摘　　要

NOVELTY - Preparation of modified epoxy/bismaleimide resin nano composite material, involves passing graphene through carboxylation and carrying out acyl-chlorination process, introducing diamine having characteristic structure or polyamines, adding amino graphene with epoxy resin/bismaleimide resin and carrying out reaction and obtaining graphene generated modified epoxy/bismaleimide resin nano composite material. USE - Preparation of modified epoxy/bismaleimide resin nano composite material (claimed). ADVANTAGE - The bonding strength of modified epoxy/bismaleimide resin nano composite material with matrix resin is increased. The overall performance of the modified epoxy/bismaleimide resin nano composite material is improved.
