Self-reinforcement of Light, Temperature-Resistant Silica Nanofibrous Aerogels with Tunable Mechanical Properties

Silica aerogels have attracted significant interest in thermal insulation applications because of their low thermal conductivity and great thermal stability, however, their fragility has limited their application in every-day products. Herein, a self-reinforcing strategy to design silica nanofibrous aerogels (SNFAs) is proposed using electrospun SiO2 nanofibers as the matrix and a silica sol as a high-temperature nanoglue. Adopting this approach...
