On January 26, 2024, the financial sector reported that, according to the announcement of the China National Intellectual Property Administration, China FAW Corporation Limited applied for a project entitled "a kind of thermal insulation and dimming glass and its preparation method", with the public number of CN117452733A and the application date of October 2023.
The patent abstract shows that the present invention relates to an insulated dimming glass and its preparation method. The insulated dimming glass comprises a first substrate glass, a Low E insulation film, a first electrochromic dimming film, a second electrochromic dimming film, and a second substrate glass arranged in sequence; The Low E insulation film comprises a first dielectric layer, a first barrier layer, a functional layer, a second dielectric layer, and a second barrier layer sequentially arranged; The first dielectric layer is adjacent to the first substrate glass; The first electrochromic dimming film and the second electrochromic dimming film both include a first transparent conductive layer, an ion storage layer, an electrolyte layer, an electrochromic layer, and a second transparent conductive layer sequentially arranged. The heat-insulating dimming glass provided by the present invention has dual color control, black anti peeping, and thermal insulation functions by designing the inner layer of the glass. At the same time, the electrochromic film is combined with offline Low E to composite in the interlayer of the car front windshield, endowing the car front windshield with multiple functionalities.
