Abstract: The present disclosure provides an article including an isoporous membrane disposed on a porous substrate. The iso-porous membrane includes a triblock copolymer or a pentablock copolymer. The isoporous membrane has a thickness and is isoporous throughout its thickness. A method of making an article is also provided, which does not require a solvent exchange process. The method includes depositing a composition on a porous substrate, thereby forming a fdm, and removing at least a portion of the solvent from the film, thereby forming an isoporous membrane having numerous pores. The composition contains a solvent and solids including a triblock copolymer or a pentablock copolymer. The article advantageously can be hydrophilic and provides sharp molecular weight cut-offs and high flux.

Abstract: A porous membrane includes a triblock copolymer of the formula ABC. B is a hydrogenated vinyl aromatic block present in a range from 30 to 90 weight percent, based on the total weight of the copolymer and has a Tg of ≥110° C. C is a rubbery block present in a range from 10 to 70 weight percent, based on the total weight of the copolymer and has a Tg≤25° C. A is substantially incompatible with both the B and C blocks and is derived from ring-opening polymerization. B+C is present in a range from 70 to 95 weight percent, based on the total weight of the copolymer.
