▎ 摘　　要

NOVELTY - Preparing graphene/high molecular composite thin film material comprises reducing graphene oxide to graphite, adding surface active agent in graphene oxide, uniformly mixing and stirring to obtain stable dispersion of high concentration graphene aqueous solution, then adding obtained graphene aqueous solution in liquid polymer, uniformly mixing and stirring to obtain liquid, and spraying obtained liquid on a substrate. USE - The method is useful for preparing graphene/high molecular composite thin film material (claimed). ADVANTAGE - The method is capable of preparing graphene/high molecular composite thin film material in simple, cost effective and eco-friendly manner.
