Manufacturing method of porous body of water-soluble polymer |
| abstract |
The present invention provides a method for producing a porous body of a water-soluble polymer with excellent simplicity. The method for producing a porous body of a water-soluble polymer disclosed herein includes: a step of preparing a solution in which a water-soluble polymer is dissolved in a mixed solvent in which water and a solvent having a higher boiling point than water are mixed; and The solution vaporizes and removes the mixed solvent. The solubility of the water-soluble polymer in the solvent having a higher boiling point than water is lower than the solubility in water. In the step of vaporizing and removing the mixed solvent, pores are formed by the solvent having a higher boiling point than water. |
