ABSTRACT:
A composite porous membrane is formed from a porous polymeric membrane having desired bulk properties on which is directly coated a cross-linked polymer having desired surface properties. The composite membrane retains the porosity of the porous polymeric membrane. The cross-linked surface polymer is produced from a crosslinkable monomer or polymer by energy from an electron beam in the absence of a chemical polymerization initiator.
