Claim 0:
1. A method of preparing an aerogel/hydrogel composite comprising:
preparing a plurality of aerogel particles including an aerogel particle having particle clusters and pores formed in a porous network of the particle clusters, and an active material supported in the pores for supplying fragrance;
preparing a polymer solution in which a polymer is dissolved in a water-soluble solvent;
mixing the plurality of aerogel particles into the polymer solution, and then homogenizing the mixture to prepare an aerogel/polymer dispersion; and
mixing the dispersion with a crosslinking agent solution to prepare an aerogel/hydrogel composite carrier,
wherein the aerogel particles are hybrid aerogel particles having a Si—CH3 group and an OH group in addition to a Si—O—Si group.
