Document Type and Number:
WIPO Patent Application WO/2019/024544
Kind Code:
A1
Abstract:
Disclosed are a self-supporting highly moisture-permeable heat insulating aerogel thin-film and a preparation method thereof. The aerogel thin-film is a single-layer thin-film supported by a SiO2 porous backbone structure itself, wherein same has a thickness of 150 to 300 μm, increases the exchange rate of vapor by 50% to 200%, and reduces the thermal conductivity coefficient by 50% to 90%. The preparation method comprises the following steps: (1) preparation of a template; (2) hydrolysis of nano-cellulose; (3) preparation of the aerogel thin-film; and (4) post-treatment of the aerogel thin-film.
