| 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 nanofiber in which nanofibers are integrated into a nonwoven fabric including a plurality of pores, Minerals are deposited on the surfaces of both sides. 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. |
