| 发明名称 | Porous film manufacturing method and apparatus | ||
| 摘要 | A method of manufacturing a porous film includes a decomposition step of introducing a porous film precursor which is formed by coagulating an undiluted film forming solution containing a hydrophilic polymer and a hydrophobic polymer, into a decomposition container; bringing a heated chemical containing an oxidizing agent into contact with the porous film precursor in the decomposition container; warming the porous film precursor in contact with the chemical; and decomposing the hydrophilic polymer remaining inside the porous film precursor using the oxidizing agent. An apparatus for manufacturing a porous film includes a decomposition device provided with the decomposition container. | ||

| 主权项 | 1. A method of manufacturing a porous film, the method comprising: coagulating an undiluted film forming solution comprising a hydrophilic polymer and a hydrophobic polymer, thereby obtaining a porous film precursor; consecutively introducing the porous film precursor into a decomposition container; bringing a heated chemical comprising an oxidizing agent into contact with the porous film precursor in the decomposition container, wherein the decomposition container is warmed by a vapor; warming the porous film precursor in contact with the chemical by traveling the porous film precursor in the vapor phase; decomposing the hydrophilic polymer remaining inside the porous film precursor in the presence of the oxidizing agent, and discharging the porous film precursor from the decomposition container. | ||
