PRODUCTION METHOD FOR POROUS POLYIMIDE RESIN FILM, POROUS POLYIMIDE RESIN FILM, AND SEPARATOR EMPLOYING SAME |
| 摘要 |
A porous polyimide resin film having a high aperture ratio, and a method for producing a porous polyimide film. The method includes removing fine particles from a polyimide resin-fine particle composite film to obtain a porous polyimide resin film by either removing at least a part of a polyimide resin portion of the polyimide resin-fine particle composite film prior to removing the fine particles, or by removing at least a part of the porous polyimide resin film subsequent to removing the fine particles. |
