Abstract
A microporous membrane and method of manufacture is presented utilizing irradiation and thermal induction phase separation techniques. During manufacture, microsphereulites are created by irradiation of curable agents in a casted polyolefin film. The microsphereulites then serve as nucleating agents in a thermally-induced phase separation step, providing a microporous membrane with improved flow and mechanical properties.
