Abstract : We developed new approaches for preparing ultrathin film composite membranes based on the anionically/electronically conductive polymers that were of interest to this research effort. Of particular interest, we developed methods for coating microporous hollow fibers with thin films of such polymers. This is important because hollow fiber supports provide the highest active surface area per unit volume of any support material. High surface area insures high permeant (e.g., anion, molecule or electron) flux. In addition, we showed that these anion/electron-conductive polymers can be used to drive electron/ion transfer reactions across membranes containing these polymers.
