WebPreparation of Regenerated Corncob Cellulose Aerogel and Film The water in the cleaned hydrogel was replaced with tert-butanol to obtain a cellulose tert-butanol gel, which was frozen in liquid nitrogen and then placed on a lyophilizer (FDU-2110, Eyela, Tokyo, Japan) to prepare the corncob cellulose aerogel by freeze drying. WebFor cellulose II, the aerogels are made via the solubilization and coagulation approach. The procedure is explained briefly as follows: cellulose is solubilized first, followed by transferring into a mold where a nonsolvent (examples are water, methanol, ethanol, isopropanol, or others) is added to exchange the higher-boiling cellulose solvent.
