It provides an airgel carrying an active material, and a composite of a hydrogel. The composite manufacturing method of the present invention comprises the steps of preparing a plurality of airgel particles having an active material in the pores, preparing a polymer solution in which a polymer is dissolved in an aqueous solvent, mixing a plurality of airgel particles into the polymer solution, and homogenizing Thus, it may include preparing an airgel/polymer dispersion and preparing an airgel/hydrogel composite carrier by mixing the dispersion with a crosslinking agent solution. According to the present invention, by preparing a hydrogel composite in which a plurality of airgel particles are distributed in a hydrogel, it is possible to provide a composite carrier capable of simultaneously storing oil and moisture without a surfactant. Furthermore, a composite carrier having improved properties such as low density, high strength, high component content, and stable desorption can be prepared. |
