NOVELTY - Preparation of aerogels involves providing 0.5-5 wt.% hydrogel containing para-aramid nanofibers, and 50.wt.% para-aramid nanofibers, preparing a frozen structure containing para-aramid nanofibers by freezing the hydrogel containing para-aramid nanofibers at less than or equal to 0 degrees C to obtain the para-aramid nanofibers, drying the frozen structure containing para-aramid nanofibers at 0-220 degrees C. USE - Preparation of aerogels containing para-aramid nanofibers (claimed). ADVANTAGE - The method can realize large-scale preparation of para-aramid nanofiber aerogel.
