| titleOfInvention | A method of coating boehmite ceramic layer on the surface of polyimide nanofiber membrane |
| abstract | A polyimide nanofiber membrane coated with a boehmite ceramic layer on the surface, the preparation method comprising: first preparing a polyamic acid nanofiber membrane by electrospinning and thermal imidization to obtain polyimide nanofibers Then the polyimide nanofibrous membrane was immersed in potassium hydroxide solution and dilute acetic acid solution for alkali solution ring-opening and acidification, then immersed in ammonia water for quaternization, and then immersed in aluminum salt solution for in-situ complexation and adsorption hydrolysis, and finally heat-treated to obtain a polyimide nanofiber membrane with a surface-coated boehmite ceramic layer. The method of the invention has the advantages of simple implementation process, high coating efficiency, green and pollution-free process, and is beneficial to expanding production. |
