▎ 摘　　要

NOVELTY - Preparing patterned three dimensional graphene conductive film involves providing a patterned seal, an oxidized graphene dispersion and a substrate where the graphene oxide dispersion contains graphene oxide and a first solvent for dispersing the graphene oxide. The oxidized graphene dispersion is applied on the patterned seal and the upper surface of the patterned seal is subjected to a rolling treatment so that the patterned seal is physically separated from the graphene oxide film to remove the patterned seal graphene oxide film and finally the obtained graphene oxide film is reduced. USE - Method for preparing patterned three dimensional graphene conductive film for preparing electronic devices (claimed). ADVANTAGE - The method enables to prepare patterned three dimensional graphene conductive film in simple, short, cost effective and eco friendly manner which is suitable for large-scale industrial production. The patterned three dimensional graphene conductive film has high strength, high flexibility, high conductivity and high picture definition. DETAILED DESCRIPTION - Preparing patterned three dimensional graphene conductive film involves providing a patterned seal, an oxidized graphene dispersion and a substrate where the graphene oxide dispersion contains graphene oxide and a first solvent for dispersing the graphene oxide. The oxidized graphene dispersion is applied on the patterned seal and the upper surface of the patterned seal is subjected to a rolling treatment so that the patterned seal is physically separated from the graphene oxide film to remove the patterned seal graphene oxide film and finally the obtained graphene oxide film is reduced to obtain three dimensional graphene conductive thin film.
