The application provides an inorganic doped electrochromic fabric and a preparation method thereof. The flexible conductive fabric is first treated with an ammonium sulfate solution for hydrophilic treatment to obtain a pretreated fabric; then a tungsten chloride anhydrous ethanol solution is prepared, and molybdenum pentachloride powder is added to prepare a precursor solution; finally, the pretreated fabric is placed in the precursor solution for high-temperature reaction, and the inorganic doped electrochromic fabric is obtained after the reaction is completed. The flexible conductive fabric is treated with the ammonium sulfate solution, functional treatment is realized, and the surface activity is improved, so that the chemical bonding between the fabric and the electrochromic film is promoted; the molybdenum pentachloride is selected as the precursor, which provides a site for the nucleation and growth of WO3 on the surface of the fabric, so that a stable WO3 and MoO3 composite film is formed, the film serves as an electrochromic layer, the fabric has excellent electrical, optical and mechanical properties, has a fast optical response time and a high coloring efficiency, and can be applied to the fields of smart clothes and implantable display.

The application discloses a high-conductivity and deep-low-temperature high-thermal-conductivity carbon film resistant to high-low temperature frequent alternation, characterized by comprising a carbon film body, the carbon film body serving as an electron donor, the carbon film body being composed of multiple layers of graphene sheet layers, a molybdenum chloride layer being inserted between two adjacent graphene sheet layers, and the molybdenum chloride layer being inserted between the graphene sheet layers in the form of an ionic compound and serving as an electron acceptor. The thermal conductivity of the carbon film can be as high as 4.6 times that of an original carbon film at deep low temperature. The carbon-based thermal-conductivity film has wide application prospects in the field of heat dissipation under extreme temperature such as aerospace and deep-sea exploration.
