| titleOfInvention | Polyamide imide solution, porous polyamide imide film, and methods for producing same |
| abstract | The present invention provides a PAI solution having a porous polyamide imide (PAI) film having excellent heat resistance, high porosity, and having continuous pores, a method for producing the same, and a method for producing the porous PAI film obtained from the solution, and a method for producing the same do. A PAI solution containing a nitrogen-containing polar solvent and an ether-based solvent, wherein the solid content concentration of the PAI is 25% by mass or less with respect to the PAI solution mass, and the content of the nitrogen-containing polar solvent is 15% by mass or more with respect to the PAI solution mass , PAI solution having a content of the ether-based solvent greater than 30% by mass relative to the mass of the PAI solution. A method for preparing the PAI solution, wherein the solid PAI is dissolved in a mixed solvent containing a nitrogen-containing polar solvent and an ether-based solvent. A method of manufacturing a porous PAI film after coating the PAI solution on a substrate and drying at a temperature of 200° C. or less. Porous PAI film produced by the above method. |
