| titleOfInvention | A kind of preparation method of polyimide/aramid nanofiber multifunctional composite thermal insulation aerogel |
| abstract | A preparation method of polyimide/aramid nanofiber multifunctional composite thermal insulation aerogel relates to a preparation method of thermal insulation aerogel. The present invention solves the problems that the existing polyimide thermal insulation aerogel processing method is complicated, the thermal insulation performance is poor, and the problems of excellent thermal insulation, thermal stability, mechanical properties, flame retardancy and hydrophobicity cannot be achieved at the same time. . Preparation methods: 1. Preparation of aramid nanofibers with high chemical activity on the surface; 2. Preparation of PI/ANF composite hydrogel of soluble polyimide and aramid nanofibers; 3. Surface functionalization of PI/ANF composite gel 4. Preparation of PI/ANF composite aerogel. The invention is used for the preparation of polyimide/aramid nanofiber multifunctional composite thermal insulation aerogel. |
