ABSTRACT = {The commercially available Polysulfone (PSF) membrane surface was modified by solution
polymerization of aniline using different oxidation catalysts i.e., FeCl<sub>3</sub>, CuCl<sub>2</sub>, 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 FeCl<sub>3</sub> and CuCl<sub>2</sub> as oxidants exhibit improved permeation, protein rejection, and antifouling properties, whereas decrement was observed in modified membrane performance using
APS as an oxidant. Among all modified membranes, PSF/PANI-CuCl<sub>2</sub>
 membrane demonstrates
the most promising performance in terms of higher pure water flux and protein solution permeation
flux i.e., 453.3 L/m<sup>2</sup>
.h and 122.3 L/m<sup>2</sup>
.h respectively. The PSF/PANI-CuCl<sub>2</sub>
 membrane unveils
superior resistance towards bio-fouling in comparison to the other modified membranes. Analytical
techniques were used for the characterization of the modified membranes such as ATR, XPS,
FESEM, and AFM. Contact angle measurement also supports the fact that PSF/PANI-CuCl<sub>2</sub>
membrane has a better chemical and physiological attachment to the polysulfone membrane
surface.},
