Graphene conductive film and preparing method therefor, and flexible touch device

A graphene conductive film and a preparing method therefor, and a flexible touch device. The method for preparing a graphene conductive film comprises: growing a graphene layer on a metal-catalyzed base (101); coating a layer of polyamic acid solution on the graphene layer, and forming a PI film by means of thermal curing (102); and removing the metal-catalyzed base to obtain a graphene conductive film having the PI film (103). The method for preparing a graphene conductive film can solve the problems that a PI film is deformed in a graphene transfer process, the yield of a transfer process is low, and graphene conductive performance is poor after transfer.
