摘要：The present disclosure provides methods for forming asymmetric membranes.More specifically, methods are provided for applying a polymerizable species to a

porous substrate for forming a coated porous substrate. The coated porous substrate isexposed to an ultraviolet radiation source having a peak emission wavelength less than340 nm to polymerize the polymerizable species forming a polymerized material

retained within the porous substrate so that the concentration of polymerized material isgreater at the first major surface than at the second major surface.
