▎ 摘　　要

NOVELTY - Graphene release agent comprises 25-35 wt.% composite nanoparticles, 1-5 wt.% dispersing agent and 60-74 wt.% deionized water. The composite nanoparticles are metal nanoparticles or metal oxide nanoparticles. The outer surface of composite nanoparticles is coated with amino group grafted graphene oxide. USE - Graphene release agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene release agent, which involves using composite nanoparticles, dispersing agent and deionized water.
