Spongy moldings comprising water-soluble polymeric material and method of controlling pores thereof |
摘要 |
A method for controlling pores of a spongy molding comprising a water-soluble polymeric material, which comprises a prefreezing step characterized in that a solution or a gel of the water-soluble material is prefreezed by cooling an interfacial side of the solution or the gel and air layer to induce a temperature slope in parallel with a direction of thickness within the solution or the gel, and a step of lyophilizing a solution or a gel of the water-soluble material prefreezed in according to the prefreezing step. Using the method for controlling pores, a spongy molding having a porous form enabling easily physical connection with the outside and the inside of sponge.
