  • Self-supporting highly moisture-permeable heat-insulating aerogel film and preparation method thereof
    Patent number: 11285442
    Abstract: The invention relates to a self-supporting highly moisture-permeable heat-insulating aerogel film and a preparation method thereof. The aerogel film is a self-supporting single-layer film with a SiO2 porous skeleton structure, having a thickness of 150 ?m to 300 ?m, which increases an exchange rate of vapor by 50% to 200%, and reduces a heat conductivity coefficient by 50% to 90%. The preparation method includes the following steps: (1) preparation of a template; (2) hydrolysis of nano-cellulose; (3) preparation of an aerogel film; and (4) post-treatment of the aerogel film.
