| description | 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. |
