| titleOfInvention | Porous film, separator for secondary battery and secondary battery |
| abstract | An object of the present invention is to provide a porous film used for a separator for a secondary battery, which has high adhesiveness to an electrode and excellent battery characteristics. SOLUTION: A porous layer A is laminated on at least one side of a porous substrate, and (1) air permeability is 50 to 1000 sec / 100 cm 3 , (2) air permeability after heat treatment at 60 ° C. for 30 minutes. The air permeability is 1.05 times or more of the air permeability before the heat treatment. (3) After performing the heat treatment of the above (2), 25% is added to a solvent composed of at least one of dimethyl carbonate, ethyl methyl carbonate and diethyl carbonate. A porous film having an air permeability of 0.95 times or less before immersion at 24 ° C. for 24 hours. [Selection diagram] None |
