▎ 摘　　要

NOVELTY - The method involves taking a substrate. Silver nano-wires are evenly coated on the substrates and dried. Silver nano-wires thin films are formed under pressure after repeated times. Silver nano-wire thin films are immersed in graphene solution. The graphene is uniformly attached to the silver nano-wire thin film. The transparent electrode composed of graphene and silver nano-wires is obtained, after drying. USE - Preparation method of transparent electrode composed of graphene and silver nano-wires used in electro-chromic device (claimed). ADVANTAGE - The oxidation resistance of graphene and the flexible characteristics of silver nano-wires can be utilized, so as to simplify the layer structure of electro-chromic devices and to improve the reaction speed of electro-chromic devices. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electro-chromic device. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating the preparation process of transparent electrode. (Drawing includes non-English language text)
