چکیده انگلیسی
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 RMgSO4 > RNaCl.
