▎ 摘　　要

NOVELTY - A transparent conductive film comprises a transparent substrate and a copper-reducing graphene oxide-shell nano-film, where the copper-reducing graphene oxide-shell nano-film is deposited on the transparent substrate. USE - Transparent conductive film for use in light transmission control device (claimed). ADVANTAGE - The transparent conductive film can be prepared with better light transmittance and conductivity, and flexible function in cost-effective manner. The light control device has better stability and reversibility. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing transparent conductive film (2) a transparent conductive film prepared by the method (3) a light transmission control device (4) a method for preparing light transmission control device (5) a light transmission control device prepared by the method.
