Title:
FLEXIBLE MULLITE FIBER AEROGEL MATERIAL AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/068737
Kind Code:
A1
Abstract:
Provided is a flexible mullite fiber aerogel material and a preparation method thereof. The method of preparing the flexible mullite fiber aerogel material comprises mixing a polymer material with a solvent to obtain a polymer solution; mixing the polymer solution with a mullite precursor and a catalyst to obtain a spinning precursor solution; performing a solution blow spinning treatment on the spinning precursor solution to obtain a composite fiber aerogel material containing the polymer material, the mullite precursor and the catalyst; and heating the composite fiber aerogel material to obtain the flexible mullite fiber aerogel material.
