Title: METHOD FOR FABRICATING COMPOSITE SIO2 AEROGEL BLANKET
Abstract:
Provided is a method for fabricating a composite SiO2 aerogel blanket; an inexpensive sodium silicate is used as a starting material; a silica sol is formed under catalysis conditions; during the sol-gel process, a fiber mat is added and, following aging, acidogenesis, surface modification, and drying at atmospheric pressure, a composite SiO2 aerogel blanket having a superhydrophobic function, ultra-low thermal conductivity, and high mechanical strength is fabricated; the method for fabricating the above is simple, safe, and low-cost, and is advantageous to large-scale fabrication of SiO2 aerogel blankets.
