Preparation,characterization and performance of conducting polypyrrole composites based on polysulfone

摘要

The poor applicability of conducting polymers due to the limitations of processibility has motivated researchers to prepare their composites.Diffusive chemical oxidative polymerization technique of pyrrole is employed to prepare polypyrrole-polysulfone(PPy-Psf)composite membranes.FTIR,TGA and AFM studies have been carried out 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 from the solution to a certain extent.The study reveals that salt rejection performance of the composite membranes depends on the FeCl3 dopant concentration,and it follows the order R_(MgSO4)>R_(NaCl).
