Moreover, the smart glasses of these two foreign companies use ITO materials as conductive electrodes, but ITO is not resistant to bending, and is prone to breakage and scrapping during production, transportation and use, and the reserves of indium ore are scarce and scattered. Difficult, with the continuous consumption of resources, the cost of ITO will continue to rise

Abstract

The invention discloses a preparation method of graphene electrochromic glass. The method comprises the following steps: 1, sequentially arranging a heating segment, a coating segment and an annealing segment along the transmission direction of a glass substrate, and sequentially assembling a graphene coating reactor and a tungsten oxide coating reactor above a glass transmission roller way in the coating segment along the transmission direction of the glass substrate; 2, heating the glass substrate in the heating segment to a preset temperature, and transmitting the heated glass substrate to the coating segment; 3, depositing a graphene film on the surface of the glass substrate by the graphene coating reactor in the coating segment, and depositing a tungsten oxide film on the surface of the graphene film by the tungsten oxide coating reactor; and 4, transmitting the coated glass substrate to the annealing segment, and annealing the coated glass substrate to finally obtain the graphene electrochromic glass. Graphene and tungsten oxide chromic films are deposited on the moving hot glass surface by using a chemical vapor deposition technology, so the obtained graphene electrochromic glass has the characteristics of sensitivity in response, and large optical modulation amplitude.

Description

technical field [0001] The invention relates to a preparation method of graphene electrochromic glass. Background technique [0002] Electrochromic technology has high barriers. Since its development in the late 1990s, only two companies in the world, Sage Glass and View in the United States, can truly master the industrialization technology. Moreover, the smart glasses of these two foreign companies use ITO materials as conductive electrodes, but ITO is not resistant to bending, and is prone to breakage and scrapping during production, transportation and use, and the reserves of indium ore are scarce and scattered. Difficult, with the continuous consumption of resources, the cost of ITO will continue to rise. [0003] As a new type of two-dimensional carbon material, graphene has the characteristics of ultra-thin, ultra-soft, high specific surface area, single atomic layer thickness and two-dimensional characteristics, coupled with good electron transport performance and w...
