▎ 摘　　要

NOVELTY - Preparing graphene anti-adhesive polycrystalline diamond composite sheet comprises (i) ball milling the graphene, catalyst and diamond to obtain mixed material, (ii) subjecting the mixture material to hydrogenation heat treatment to obtain hydrogenated material, and (iii) sintering the hydrogenated material to obtain graphene anti-adhesive polycrystalline diamond composite sheet. USE - The method is useful for preparing graphene anti-adhesive polycrystalline diamond composite sheet. ADVANTAGE - The sheet has good anti-adhesive and wear resistance performance, and has abrasion ratio of 2.5-3x 104. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene anti-adhesive polycrystalline diamond composite sheet.
