Self-growing nanowire reinforced silicon carbide aerogel material and preparation method thereof
The invention discloses a self-growing nanowire reinforced silicon carbide aerogel material and a preparation method thereof.The preparation method comprises the steps that ethyl alcohol, terephthalaldehyde, siloxane, amino siloxane, deionized water and acid are evenly mixed and fully react to obtain sol; heating the sol to obtain gel A; carrying out multiple times of organic solvent replacement on the gel A, and then drying to obtain aerogel A; soaking the aerogel A in the sol prepared in the first step to obtain a mixture; heating the mixture to obtain gel B; replacing the gel B with an organic solvent, and drying to obtain aerogel B; and repeatedly dipping, heating, replacing and drying, and finally carrying out high-temperature heat treatment on the aerogel to obtain the self-growing nanowire enhanced silicon carbide aerogel.
本申请公开了一种自生长纳米线增强碳化硅气凝胶材料及其制备方法，将乙醇、对苯二甲醛、硅氧烷、氨基硅氧烷、去离子水和酸混合均匀，充分反应得到溶胶；溶胶加热制得凝胶A；凝胶A进行多次有机溶剂置换后进行干燥得到气凝胶A；气凝胶A浸渍于第一步制得的溶胶中得到混合物；混合物加热得到凝胶B；凝胶B进行有机溶剂置换后进行干燥得到气凝胶B；重复浸渍、加热、置换和干燥，最终气凝胶进行高温热处理得到自生长纳米线增强的碳化硅气凝胶。
