▎ 摘　　要

NOVELTY - A graphite is provided to solid-phase ball milling, to obtain multi-layered nano-graphite sheet. Multi-layered graphite powder is ultrasonically dispersed in organic polar solvent, to obtain graphene suspension. The obtained graphene suspension and metal chloride salt aqueous solution are mixed, and metal salt ion intercalation is absorbed on graphene layer. The unsaturated carboxylic acid and sodium hydroxide solution are added, stirred, rotated and evaporated to remove solvent, to obtain unsaturated carboxylic acid zinc salt functionalized graphene. USE - Preparation of unsaturated carboxylic acid zinc salt functionalized graphene. ADVANTAGE - The unsaturated carboxylic acid zinc salt functionalized graphene is efficiently prepared. DETAILED DESCRIPTION - A graphite is provided to solid-phase ball milling, to obtain multi-layered nano-graphite sheet. The multi-layered graphite powder is ultrasonically dispersed in an organic polar solvent, to obtain graphene suspension. The obtained graphene suspension and metal chloride salt aqueous solution are mixed ultrasonically, and metal salt ion intercalation is absorbed on the graphene layer. The unsaturated carboxylic acid and sodium hydroxide solution are added under the ultrasonic physical effect, stirred uniformly, rotated and evaporated to remove the solvent, to obtain unsaturated carboxylic acid zinc salt functionalized graphene.
