Hafnium oxide ceramic nanofiber and preparation method thereof
The invention discloses hafnium oxide ceramic nanofibers and a preparation method thereof. The preparation method comprises the following steps: firstly, dissolving a high polymer material in a proper solvent to obtain a high polymer solution with certain viscosity; then adding a hafnium oxide precursor into the polymer solution to obtain a spinning precursor mixed solution; spraying the precursor mixed solution onto a receiver by adopting a solution jet spinning method to obtain a composite fiber; and finally, carrying out heat treatment on the obtained composite fiber at a certain temperature to obtain the hafnium oxide ceramic nanofiber. The preparation process is simple, the cost is low, the efficiency is high, and the hafnium oxide ceramic nanofiber prepared by the method is relatively good in flexibility and resistant to high temperature, and has a good application prospect in the fields of aerospace, high-temperature air filtration, catalyst carriers, fireproof suits and the like.
