Abstract

The invention provides aerogel composite electrochromic glass and a preparation method thereof. The aerogel composite electrochromic glass comprises a first substrate, a PVB tape casting film layer, a second substrate and an aerogel filling layer which are sequentially arranged, the key points of the technical scheme are as follows: a first substrate comprises a first substrate, a first anti-reflection dielectric film layer, a barrier layer, a conductive layer, a first transparent conductive layer and a cathode color-changing layer which are sequentially arranged in a composite manner; a second substrate comprises a second substrate, a second anti-reflection dielectric film layer, a second transparent conductive film layer and an anode color-changing layer which are sequentially arranged in a composite manner; according to the aerogel composite electrochromic glass, the problem of light transmission performance control is solved, and especially when visible light and near-infrared light are in different wavelength bands, automatic color regulation and control, light adjustment and temperature adjustment are better achieved.

Description

technical field [0001] The invention relates to the technical field of color-changing film glass, in particular to an aerogel composite electrochromic glass and a preparation method thereof. Background technique [0002] The color-changing glass can automatically adjust the transmittance of visible light and infrared light, which satisfies the development of different energy-saving glass for different latitudes, and cannot meet the energy-saving needs of winter and summer at the same time. Electrochromism refers to a phenomenon in which a material changes its color due to a reversible oxidation or reduction reaction caused by the change in the polarity and intensity of an applied electric field. Electrochromic smart glass can not only adjust the transmittance of visible light, but also has a blocking effect on infrared light, so as to adjust the temperature of the interlayer area, and can adjust the transmission and reflection according to the electrochromic material. Due t...
