▎ 摘 要
NOVELTY - A graphite oxide is dispersed in dispersion medium to obtain graphene oxide dispersion. Polyvinyl alcohol is mixed with graphene oxide dispersion to obtain graphene oxide-polyvinyl alcohol complex solution. The graphene oxide-polyvinyl alcohol complex solution is chemically reduced to obtain graphene dispersion. The graphene dispersion is dried to obtain graphene film. USE - Manufacture of graphene film (claimed). ADVANTAGE - The method enables manufacture of graphene film having excellent electroconductivity.
