Since there is no surface tension in the supercritical fluid, there is no additional pressure in the gel capillary pores caused by surface tension at this time. Therefore, the use of the gel under supercritical fluid conditions is boring, the collapse of the gel structure caused by additional pressure does not occur, the shrinkage of the gel during drilling is avoided, and the gel mesh frame structure is adhered to the ultrafine aerogel with high specific surface area, uniform particle size distribution and large pore volume.
