The present invention relates to a porous support, a method for producing the same, and a reinforced membrane including the porous support. The porous support includes a nanoweb in which nanofibers are integrated in the form of a nonwoven fabric having a large number of pores, The saturation moisture content arrival time of the nanoweb is 1 second to 600 seconds. The porous support not only has excellent air permeability and water permeability, but also has excellent durability, heat resistance, and chemical resistance, as well as excellent hydrophilicity. |
