Abstract

The invention includes methods of reversibly tuning the effective pore size and/or solute rejection selectivity of a nanoporous lyotropic liquid crystal (LLC) polymer membrane. The membranes of the invention have high levels of pore size uniformity, allowing for size discrimination separation, and may be used for separation processes such as liquid-phase separations.
