| titleOfInvention | SiO based on electrostatic spinning2Nanofiber aerogel heat insulation material and preparation and application thereof |
| abstract | The invention relates to a method for preparing SiO based on electrostatic spinning 2 Firstly, preparing SiO (silicon dioxide) aerogel thermal insulation material and preparation and application thereof 2 Nano-fiber, then preparing fiber/functional polymer composite dispersion liquid; then, pre-freezing the dispersion liquid, and then removing the solvent of the dispersion liquid to form the polymer/fiber-based aerogel; then the modified SiO is prepared by high-temperature calcination treatment 2 A nanofiber aerogel thermal insulation material. SiO prepared by the invention 2 The aerogel keeps good heat insulation performance and mechanical property in high and low temperature environment, has good flexibility, and greatly improves the common SiO 2 The problems of large brittleness and poor mechanical property of the aerogel; the density is low and can be as low as 2.0mg/cm 3 (ii) a The thermal conductivity can be as low as 0.02W/(mK). The method has simple process, easy operation and good application prospect. |
