Polyamide imide solution, porous polyamide imide film, and methods for producing same |
| abstract |
The present invention provides a PAI solution which is excellent in heat resistance and has a high porosity and has continuous pores and which can obtain a porous polyamide imide (PAI) film, a process for producing the same, and a porous PAI film obtained from the solution and a process for producing the same do. Wherein the solid content concentration of the PAI is 25 mass% or less with respect to the mass of the PAI solution, the content of the nitrogen-containing polar solvent is 15 mass% or more with respect to the mass of the PAI solution , And the content of the ether-based solvent is more than 30 mass% with respect to the mass of the PAI solution. A method for producing the above PAI solution, which comprises dissolving solid PAI in a mixed solvent containing a nitrogen-containing polar solvent and an ether-based solvent. Applying the PAI solution to a substrate, and drying the PAI solution at a temperature of 200 DEG C or less. A porous PAI film produced by the above method. |
