▎ 摘　　要

NOVELTY - Electrochromic plexiglass comprises a double-layer plexiglass substrate, a first conductive layer, a tungsten oxide/reduces graphene oxide (RGO) electrochromic layer, a vanadium oxide/RGO ion storage layer, an ion conductive layer and a second conductive layer are sequentially sandwiched between the double-layer organic glass substrates. USE - The electrochromic plexiglass is used in building glass windows or car windows, including automobile, high-speed rail, station, car park, balcony, stadium, exhibition hall door and window, roof and display screen. ADVANTAGE - The electrochromic plexiglass realizes the transmission and regulation of light in various bands such as visible light and infrared light alone or at the same time, when it is applied to it can achieve the effect of protecting indoor privacy and keeping warm in winter and cool in summer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the electrochromic plexiglass comprising (a) adding tungsten oxide and redox graphene, adding to ethanol, and dispersing to obtain tungsten oxide/RGO composite sol, adding tungsten oxide/RGO composite sol into the dispersion slurry and disperse to obtain tungsten oxide/RGO electrochromic material, (b) adding vanadium oxide and redox graphene, adding to ethanol, and dispersing to obtain vanadium oxide/RGO composite sol, adding vanadium/RGO composite sol to the dispersion slurry and disperse to obtain vanadium/RGO ion storage material, (c) adding the conductive substrate, adding it to the dispersion slurry, and dispersing to obtain the conductive material, and (d) adding a layer of plexiglass substrate, and coat the surface of the plexiglass substrate with conductive material I, tungsten oxide/RGO electrochromic material, vanadium oxide/RGO ion storage material, covering the ion-conducting material and the conductive material II with a layer of plexiglass substrate on the surface of the conductive material II.
