▎ 摘　　要

NOVELTY - Unsaturated carboxylic acid metal salt/graphene oxide composite material comprises an unsaturated carboxylic acid metal salt and graphene oxide compounded on the surface of the unsaturated carboxylic acid metal salt. USE - Unsaturated carboxylic acid metal salt/graphene oxide composite material used as rubber composite material (claimed). ADVANTAGE - The unsaturated carboxylic acid metal salt/graphene oxide composite material has no additional modified materials, which reduces the risk of rubber composite materials. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for following: (1) a method for preparing an unsaturated carboxylic acid metal salt/graphene oxide composite material, which involves mixing the graphene oxide dispersion liquid, soluble metal salt and water to obtain mixed liquid; (2) mixing obtained mixed solution, soluble unsaturated carboxylic acid and the alkali solution and then performing reaction to obtain an unsaturated carboxylic acid metal salt/ graphene oxide composite material; and (3) a rubber composite material, which comprises unsaturated carboxylic acid metal salt/graphene oxide composite material.
