Abstract The commercially available Polysulfone (PSF) membrane surface was modified by solution
polymerization of aniline using different oxidation catalysts i.e., FeCl3, CuCl2, and APS. Modified
membranes were then characterized with respect to physio-chemical properties like surface
chemistry, porosity, wettability, surface roughness, morphology, etc. It was observed that the
hydrophilicity/ wettability of membranes was increased upon surface modification by polyaniline
which again depended on the nature of the oxidation catalyst used. Membranes developed
using FeCl3 and CuCl2 as oxidants exhibit improved permeation, protein rejection, and antifouling properties, whereas decrement was observed in modified membrane performance using
APS as an More >
