Nanoporous polysulfones with in situ PEGylated surfaces by a simple swelling strategy using paired solvents

Abstract

We report the formation of three-dimensionally interconnected nanoporosities with in situ PEGylated pore walls simply by swelling the block copolymers of polysulfone and poly(ethylene glycol) in paired solvents. The produced nanoporous polymers are expected to find important applications in membranes, batteries, chromatography, and haemodialysis.
