▎ 摘　　要

NOVELTY - Preparing graphene/polymer composite conductive film involves mixing polymer matrix and the solvent to form a solution to form a first mixed solution, adding graphene to an equal volume of the same solvent, dispersing the graphene sheet by ultrasonic treatment, and then pouring the dispersed graphene suspension into the first mixed solution and stirring to form a second mixed solution. After vacuum defoaming the second mixed solution under vacuum, applying it on various substrates, and drying at normal temperature and pressure to form a graphene / polymer composite conductive film. USE - Method for preparing graphene/polymer composite conductive film. ADVANTAGE - The method enables to prepare graphene/polymer composite conductive film with good electrical conductivity and can be tightly combined with various substrates. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene/polymer composite conductive film.
