[Abstract]: Flexible SiO2 nanofibers were prepared by electrospinning, and then mixed with hydrophilic gas phase SiO2, then SiO2 composite thermal insulation materials were prepared by semi dry pressing. The results show that the flexible SiO2 fiber provides a space network framework for hydrophilic gas-phase SiO2, and improves its flexural strength without significantly improving its thermal conductivity.
