Abstract
The disclosure provides a very simple and convenient method for producing a porous material of a water-soluble polymer. The herein disclosed method for producing a porous material of a water-soluble polymer includes a step of preparing an emulsion containing a water-soluble polymer, water, and a dispersoid, wherein the water-soluble polymer is dissolved and the dispersoid is dispersed in the emulsion, and a step of evaporating and thereby removing the water and the dispersoid from the emulsion. The boiling point of the dispersoid is higher than the boiling point of water. The solubility of the water-soluble polymer in the dispersoid is lower than the solubility of the water-soluble polymer in water.
