| titleOfInvention | Porous polyimide film |
| abstract | Provided is a porous polyimide film useful as a battery separator without heating at an extremely high temperature or treatment with a special chemical. A porous polyimide film obtained by the procedures of (a) to (c). (A) Polyimide and a compound A having a weight average molecular weight of 100 to 1500 as a solid content and a mixed liquid using an organic solvent as a solvent are prepared, (b) a film is formed using the mixed liquid, and (c) The film is immersed in a solvent in which compound A is dissolved to remove compound A from the film. The polyimide is a polyimide having a phenylene skeleton and an isopropylidenebis (p-phenyleneoxy) skeleton, the organic solvent is a halogen solvent having a boiling point of less than 100 ° C., and the compound A is a polyalkylene glycol compound. A porous polyimide film in which the solvent in which the compound A is dissolved is at least one selected from water, methanol, ethanol, propanol and the like. [Selection figure] None |
