Porous membrane, composite membrane, and method for producing porous membrane or composite membrane |
| abstract |
The present invention pertains to a porous membrane comprising a porous resin layer that contains a polymer containing a polyvinylidene fluoride resin as a main component, wherein: a branched polyvinylidene fluoride resin is contained as the polyvinylidene fluoride resin; the porous resin layer has a surface with an average pore size of 0.01-0.1 μm; the porous resin layer has macrovoids with a minor axis of at least 50 μm; and the polymer has an a value of 0.27-0.39 and a b value of 0.22-0.60 which are approximately determined by equation 1 using the radius of gyration <S 2 > 1/2 and the absolute polymer molecular weight M w as measured with gel permeation chromatography with a multi-angle light scattering detector (GPC-MALS). <S 2 > 1/2 =bM w n a ∙∙∙ (Equation 1) |
