| titleOfInvention | Deformable aerogel material and preparation method thereof |
| abstract | The invention relates to a deformable aerogel material and a preparation method thereof. The method comprises the following steps: performing polycondensation reaction by using dianhydride and diamine as monomers, adding 1,1, 1-tris [4- (aminophenoxy) phenyl ] ethane as a curing agent to obtain a polyamic acid solution, adding fumed silica nanoparticles to obtain the polyamic acid solution doped with the fumed silica nanoparticles, and performing thermal imidization on the polyamic acid solution by treating the polyamic acid solution in a vacuum oven and heating procedures at different temperature stages to obtain polyimide wet gel; and (3) sequentially carrying out aging, solvent replacement and supercritical drying on the polyimide wet gel to prepare the deformable aerogel material. The aerogel material can be deformed and fixed under the heating condition, can recover the shape under the next thermal response, and has good temperature resistance, and the aerogel material has the advantages of high porosity (88-99 percent), high shape recovery rate (90-100 percent), adjustable deformation and recovery temperature and the like. |
