Abstract: The present invention includes a patterned thin film membrane and a patterned thin film composite membrane. The present invention also includes a method of making and using the patterned membranes of the invention. In certain embodiments, the thin film membrane comprises a first surface and a second surface counterfacing the first surface. In other embodiments, a repeating pattern covers a portion of a working area of the thin film membrane. In yet other embodiments, the periodicity of the repeating pattern is equal to or lower than about 1 micrometer in size. In yet other embodiments, the repeating pattern covers a portion of at least one selected from the group consisting of the first surface and the second surface of the thin film membrane.

Abstract: A membrane for fluid transfer includes a base membrane and a pattern, that covers a working area of a surface thereof, formed of a compatible material. The pattern has periodicity and/or amplitude that do not exceed 1 micrometer. A method of filtering a component from a solution includes passing the solution comprising the component through a membrane that includes a base membrane. The base membrane and a pattern that covers a working area of a surface thereof are formed of materials compatible with the solution. The pattern has periodicity and/or amplitude that do not exceed 1 micrometer, and reduces mass transfer of surface-accumulative soluble and/or suspended species and particulates from the solution to the membrane while the solution is passed through the membrane. A method of producing a membrane for fluid transfer includes forming a nanoscale pattern over a working area of a polymer membrane.
