  • COATED ASYMMETRIC MEMBRANE SYSTEM HAVING OLEOPHOBIC AND HYDROPHILIC PROPERTIES
    Publication number: 20080241504
    Abstract: A porous membrane assembly includes, in an exemplary embodiment, a porous membrane substrate having hydrophobic properties. The membrane substrate includes a first side, an opposing second side and a plurality of pores extending therethrough. The membrane substrate also includes a discontinuous layer of an oleophobic coating applied to the first side so that the plurality of pores in the first side are substantially free of the oleophobic coating, and a continuous layer of an amine containing hydrophilic polymer coating applied to the second side of the membrane substrate.
