▎ 摘  要

NOVELTY - Electrochromic device comprises a first multilayer thin film structure (210) connected to a first electrode of an external power source and comprises a first graphene layer (216) and a first metal protective layer (214) formed on the first graphene layer to protect the first graphene layer from oxygen. The second multilayer thin film structure (220) is connected to a second electrode of the external power source and comprising a second graphene layer (226) and a second metal protective layer (224) formed on the second graphene layer to protect the second graphene layer from oxygen, and an electrolyte is charged between the first multilayer thin film structure and the second multilayer thin film structure. USE - Electrochromic device used in the smart windows also get into the spotlight. ADVANTAGE - The electrochromic device enables to reduce energy loss and improve energy efficiency, and provides a comfortable environment for users. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for making an electrochromic device by using a multilayer thin film structure, comprises a graphene layer, which involves: forming a first multilayer thin film structure connected to a first electrode of an external power source and comprises a first graphene layer and a first metal protective layer formed on the first graphene layer to protect the first graphene layer; forming a second multilayer thin film structure connected to a second electrode of the external power source and comprising a second graphene layer and a second metal protective layer formed on the second graphene layer to protect the second graphene layer; and charging an electrolyte between the first multilayer thin film structure and the second multilayer thin film structure.
