Abstract

The poor applicability of conducting polymers due to the limitations of processibility has motivated researchersto prepare their composites. Diffusive chemical oxidative polymerization technique of pyrrole is employed toprepare polypyrrole-polysulfone (PPy-Psf) composite membranes. FTIR, TGA and AFM studies have been carriedout to provide evidence for incorporation of pyrrole moiety as well as to characterize the composites. The polysulfone-polypyrrole composite membranes show the potential of removing sodium chloride and magnesium sulfate fromthe solution to a certain extent. The study reveals that salt rejection performance of the composite membranesdepends on the FeCl₃ dopant concentration, and it follows the order R_MgSO4 > R_NaCl.
