The invention relates to an MXene/polyimide nanofiber aerogel and a preparation method and application thereof, which solve the problems of poor shielding performance of existing materials, high technological difficulty, and inability to meet certain requirements on the three-dimensional shape or mechanical properties of materials. The technical problem is that it contains MXene and polyimide fibers, the polyimide fibers are polyimide nanofibers, the polyimide nanofibers are in the form of a network, and the MXene is distributed in the polyimide nanofibers in the form of flakes. The thickness of the aerogel is 2mm˜8mm. The invention also provides its preparation method and application. The invention can be used in the field of preparation of electromagnetic shielding functional materials. |
