Aerogel is an ultra-porous material derived from a gel, in which the liquid component of the gel has been replaced with air. Usually it is prepared by a supercritical drying using carbon dioxide. In this study, we tried to prepare aerogel by other drying, that is, by a solvent-exchange treatment and then a heat-drying at ambient pressure, and by a freeze-drying with an antifreeze protein. Some samples had many macropores like the aerogel prepared by the supercritical drying.
