文摘
Fumed silica based thermal insulating composite was prepared by a novel method. Fumed alumina was added as an inhibitor to limit thermal shrinkage. The mechanism was investigated by molecular dynamics simulation. Thermal insulating property was comprehensively studied. The effect of fumed alumina on thermal conductivity was analyzed.
