Abstract: The disclosure provides porous membranes capable of removing very small particulates from a liquid composition. In certain embodiments, the porous membranes comprise poly(tetrafluoroethylene), wherein the membrane is at least partially coated with a polymer prepared from the free radical reaction of ethylenically-unsaturated monomers, wherein the monomers are comprised of monomers having an amide moiety. In particular embodiments, the membranes are capable of removing, by filtration, microbial particles such as bacteria, thus rendering the resulting liquid composition essentially sterile.

Abstract: A polysulfone membrane is modified so that monomers are grafted onto the surface of the membrane. The polysulfone membranes can be grafted by contacting the membrane with a grafting solution and exposing the membrane to electromagnetic radiation, typically within the ultraviolet portion of the spectrum. The monomers that are grafted are typically anionic or cationic. The grafted membranes can be used for filtering impurities, such as positively and negatively charged particles, from a liquid. Anionic membranes provide improved filtration of negatively charged impurities, while cationic membranes provide improved filtration of positively charged impurities.
