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 a solution in which a water-soluble polymer is dissolved in a mixed solvent of water mixed with a solvent having a boiling point higher than that of water, and a step of evaporating and thereby removing the mixed solvent from the solution. The solubility of the water-soluble polymer in the solvent having a boiling point higher than that of water is lower than the solubility of the water-soluble polymer in water. Voids are formed, in the step of evaporating and thereby removing the mixed solvent, by the solvent having a boiling point higher than that of water.

Disclosed are methods of making porous polymeric materials. Also provided herein are porous polymeric materials prepared by the disclosed methods.
