Abstract
An aerogel carrying an active material, and a composite of a hydrogel and the aerogel are provided. The method for preparing the composite according to the present invention comprises the steps of preparing a plurality of aerogel particles having an active material in the pores, preparing a polymer solution in which a polymer is dissolved in a water-soluble solvent, preparing an aerogel/polymer dispersion by homogenizing after mixing the aerogel particles in the polymer solution, and preparing an aerogel/hydrogel composite carrier by mixing the dispersion with a crosslinking agent solution. According to the present invention, by producing a hydrogel composite in which a plurality of aerogel particles is distributed, a complex carrier in which oil and moisture can be carried simultaneously without any surfactant can be provided. Furthermore, a composite carrier having improved properties such as low density, high strength, high component content and stable desorption can be prepared.
