The invention provides systems and methods for substantially improving the compaction resistance of isoporous block copolymer (BCP) film by adding a high molecular weight hydrophilic additive in the casting dope formulation. Systems and methods disclosed also disclose several other multifunctional enhancements to film properties including: low fouling propensity, improved permeability, improved permeability retention upon drying, and ability to tune the substructure and pore size of these novel BCP films. These porous BCP films are useful in filtration and separations applications and are amenable to standard manufacturing practices.

A mesoporous isoporous asymmetric material includes at least one diblock or multiblock copolymer, wherein the material has a transition layer having a thickness of at least 300 nm and a low macrovoid density, and the material has a sub-structure adjacent to said transition layer and said sub-structure comprises a high macrovoid density. A method for producing mesoporous isoporous asymmetric materials having macrovoids can include: dissolving at least one diblock or multiblock copolymer in a solution, the solution having one or more solvents and one or more nonsolvents, to form a polymer solution; dispensing the polymer solution onto a substrate or mold, or through a die or template; removing at least a portion of solvent and/or nonsolvent from the polymer solution to form a concentrated polymer solution; and exposing the concentrated polymer solution to a nonsolvent causing precipitation of at least a portion of the polymer from the concentrated polymer solution.
