<p>The present invention is to provide a method of showing a moisture adsorption amount of quite high numerical value compared to a normal high temperature and low pressure dying process as salt is highly dispersed in a silica structure and the particle size of salt becomes smaller. To this end, the method for manufacturing a moisture adsorption and desorption material comprises the steps of; preparing silica, salt, and distilled water; preparing an impregnated liquid by dissolving the salt into distilled water; manufacturing a mixture by mixing and stirring the silica to the impregnated liquid; and manufacturing the moisture adsorption and desorption material by freeze-drying the mixture.</p> |
