Abstract

The invention provides a cyclodextrin composite ceramic precursor with a gel spinning function and a preparation method thereof. The cyclodextrin composite ceramic precursor with the gel spinning function comprises element macromolecules, cyclodextrin and a gel inducer, or is prepared in the following steps that the element macromolecules are dissolved in a solvent to be prepared into an element macromolecule solution, the gel inducer is added into the element macromolecule solution to prepare an element macromolecule-gel inducer solution, the cyclodextrin is dissolved in the solvent to prepare a cyclodextrin solution, the element macromolecule-gel inducer solution is added into the cyclodextrin solution and stirred evenly to form cyclodextrin composite ceramic precursor sol, the cyclodextrin composite ceramic precursor sol is heated so that the gel inducer and the cyclodextrin can be assembled, and cyclodextrin composite ceramic precursor gel is formed.

Description

technical field [0001] The disclosure relates to a cyclodextrin composite ceramic precursor with gel spinning function and a preparation method thereof. Background technique [0002] Ceramic fiber is a fibrous material with light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and high strength. Due to the above excellent comprehensive properties, ceramic fibers have been widely used in machinery, metallurgy, chemical industry, petroleum, electronics, aerospace, national defense and other industries. In terms of composition, ceramic fibers mainly include alumina ceramic fibers, zirconia ceramic fibers, silicon nitride ceramic fibers, silicon carbide ceramic fibers, and boride ceramic fibers. Fibers with different components have different high temperature resistance, corrosion resistance, dielectric constant, radiation resistance, mechanical strength, etc., so the advantages of their respective applications are also...
