| abstract |
The present invention relates to a porous support, a method for producing the same, and a reinforcing membrane comprising the same, wherein the porous support comprises a nano-web in which polyimide nanofibers are integrated into a nonwoven fabric including a plurality of pores, The backbone comprises a hydrophilic substituent. The porous support is excellent in durability, heat resistance, and chemical resistance as well as excellent in hydrophilicity because it has excellent air permeability and water permeability. |
