Abstract

ABSTRACTNovel macro and meso porous polysulfone materials were prepared from miscible blends of polysulfones with a phenylindane containing polyimide by chemically decomposing the polyimide phase with a dilute hydrazine solution in methanol. The polyether sulfone meso porous membranes are transparent films, with uniform pore sizes in the range of 30 nm. On the other hand, bisphenol A polysulfone based porous materials are opaque with pore sizes in the range of 200 nm.
