Enhancement of polycarbonate membrane permeability due to plasma polymerization precursors

► We modify surface of track-etched polycarbonate membranes by plasma polymerization technique with monomers seperately; acrylic acid and allylamine. ► We examine changes in the level of permeations on membranes after modifications. ► To use of acrylic acid as precursor decrease diffusion of target molecule on membrane. ► To use of allylamine as precursor increase diffusion of target molecule on membrane ► Plasma modification could be new approach for filtration with the selection of monomer in process depend on target species is the key idea.
