Title:
AEROGEL COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/077677
Kind Code:
A1
Abstract:
An aerogel composite material, a preparation method therefor, and the use thereof. The aerogel composite material comprises a polymer aerogel and an inorganic nano aerogel, the polymer aerogel being an aerogel prepared from at least one of aramid fiber, poly(p-phenylenebenzobisoxazole) and polyimide, and the inorganic nano aerogel comprising silicon dioxide aerogel. In the aerogel composite material, the inorganic nano aerogel permeates into and uniformly fills the space in the polymer aerogel, such that the aerogel composite material has good mechanical properties, heat insulation properties and high-temperature resistance, and therefore can be used in a plurality of fields such as engineering fireproof materials or lithium ion battery packs, and has a good application prospect.
