NOVELTY - The preparation of aqueous graphene electro-thermal film involves subjecting graphene to hydrophilization treatment, adding cellulose derivative solution as dispersant and thickener, pre-dispersing, adding additive to pre-dispersed graphene to obtain homogeneous dispersing liquid, adding binder to dispersing liquid, stirring, mixing to obtain graphene electric film paste, coating graphene electric heating film paste on film-forming carrier to form graphene conductive layer and drying. The graphene electro-thermal film is composed of graphene conductive layer and film-forming carrier. USE - Preparation of aqueous graphene electro-thermal film (claimed). ADVANTAGE - The method enables preparation of aqueous graphene electro-thermal film with excellent thermal conductivity.
