| titleOfInvention | A high-performance bulk aramid nanofiber aerogel and its preparation method and application |
| abstract | The invention relates to a high-performance bulk aramid nanofiber aerogel and a preparation method and application thereof. The preparation method includes: (1) nano-forming Kevlar macroscopic fibers to prepare an aramid nanofiber colloidal dispersion; (2) preparing a bulk aramid nanofiber hydrogel by a solvent exchange phase transition method; (3) using Bulk aramid nanofiber aerogels were prepared by drying processes such as supercritical CO 2 and atmospheric pressure. The preparation method of Kevlar aerogel provided by the invention has simple process, is easy to realize continuous and large-scale production, and can prepare nanofiber aerogel with adjustable density and mechanical properties; the high-performance Kevlar aerogel provided by the invention Aerogels have high specific surface area, adjustable density, controllable porosity, low thermal conductivity, and high temperature resistance. |
