Document Type and Number:
WIPO Patent Application WO/2019/143205
Kind Code:
A1
Abstract:
Provided are: an aerogel having an active material loaded therein; and a complex of the aerogel and a hydrogel. A method for manufacturing the complex of the present invention may comprise the steps of: preparing a plurality of aerogel particles including an active material in pores; preparing a polymer solution in which a polymer is dissolved in an aqueous solvent; mixing the plurality of aerogel particles with the polymer solution, followed by homogenization, to prepare an aerogel/polymer dispersion; and mixing the dispersion with a crosslinker solution to produce an aerogel/hydrogel complex carrier. According to the present invention, a hydrogel complex in which a plurality of aerogel particles are distributed in a hydrogel is prepared, and thus a complex carrier capable of storing both oil and moisture without a surfactant can be provided. Furthermore, a complex carrier having improved characteristics, such as low density, high strength, high component content, and stable detachment, can be produced.
