MULTIBLOCK COPOLYMER FILMS, METHODS OF MAKING SAME, AND USES THEREOF

摘要

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 x 1014 pores/m2 and a pore size distribution (dmax/dmin)) of less than 3. The bulk layer has an asymmetric structure. The films can be used in filtration applications.
