Multi-layer porous block copolymer films

Abstract

The present disclosure relates to methods of making multi-layered graded multiblock copolymer films; multi-layered graded multiblock copolymer films made by the disclosed methods; uses of the disclosed multi-layered graded multiblock copolymer films; and devices comprising the disclosed multi-layered graded multiblock copolymer films. An exemplary disclosed multi-layered graded multiblock copolymer film has at least three identifiable layers comprising a first porous “skin” layer formed on the surface of a substrate, a porous bulk layer formed on the first porous “skin” layer, and a second porous “skin” layer formed on the surface of the porous bulk layer. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
