Abstract
A polymer solution is created by mixing an olefin-based resin and a solvent in a pressure vessel. A high-pressure fluid of carbon dioxide is created. Temperature of the high-pressure fluid is adjusted. A mixed fluid is created by mixing the high-pressure fluid of which the temperature is adjusted and the polymer solution in the pressure vessel. Cooling of the mixed fluid causes phase separation of the mixed fluid to occur. After phase separation, pressure in the pressure vessel is released, and the solvent and the carbon dioxide vaporize. The vaporizing of the solvent and the carbon dioxide creates a porous medium of olefin-based resin.
