Fabrication of SiCN(O) Aerogel Composites with Low Thermal Conductivity by Wrapping Mesoporous Aerogel Structures over Mullite Fibers.

Unlike the aerogels prepared using crosslinkers with rigid groups exhibiting a relatively large decrease in specific surface area and pore volume after the process of pyrolysis conversion, aerogels synthesized under the effect of the cross-linking agent with flexible carbon chains showed an increasing trend [ 15 , 32 , 33 ].
