Claim 0:
1. A coated substrate, comprising:
a polyolefin substrate having a functional polymer layer disposed thereon;
wherein the polyolefin substrate has a flow through pore structure with a pore size ranging from about 5 microns to about 250 microns; and
the functional polymer layer having a thickness ranging from about 1 micron to about 20 microns, and a layer pore structure having a pore size ranging from about 1 nm to about 100 nm,
wherein the functional polymer layer is not covalently bound to the polyolefin, and the functional polymer layer has a surface area of from about 25 m2/g to about 800 m2/g,
wherein the functional polymer layer is formed from one or more porogen, one or more monomer, and a polymerization initiator, and the monomer comprises styrene, divinylbenzene, vinylbenzylchloride, acrylates, methacrylates, ethylvinylbenzene, derivatives thereof, and combinations thereof.
