Abstract

A method for forming an isoporous graded film comprising multiblock copolymers and isoporous graded films. The films have a surface layer and a bulk layer. The surface layer can have at least 1×10pores/mand a pore size distribution (d/d)) of less than 3. The bulk layer has an asymmetric structure. The films can be used in filtration applications.
