Summary

Novel charge-mosaic composite membranes were successfully prepared using novel polymer precursors. The resulting membranes, poly(isoprene-4-methylstyrene) diblock copolymer (IMs)/poly(isoprene-styrene-isoprene) triblock copolymer (ISI) and poly(4-methylstyrene-isoprene-styrene-isoprene-4-methylstyrene) pentablock copolymer (MsISIMs), exhibited similar structures and properties.
