In this paper, we propose a preparation technology of graphene films by self-assembly method. By employing this technology, the high conductive transparent and uniform graphene films are obtained. Its various parameters are tested and spectral characteristics are studied. Research shows that the graphene films prepared by this method has the advantages of low impurity content, high conductive, high transparent and controllable film thickness, etc. Its average transmittance arrive at 80% and minimum square resistance can reach 0.2 Ω/sq. This graphene films has important application prospect at the transparent electrode and an organic optoelectronics fields.
