Characterization of chemical grafting of polyaniline onto wool fiber

Polyaniline grafted wool fiber was prepared by a chemical polymerization method using potassium peroxydisulfate (PDS) as a lone initiator under optimized conditions. The simultaneous homopolymer formed, as well as physisorbed polyaniline (PANI) onto wool fiber, were removed by a systematic procedure. The isolation procedure was quantified through UV-visible spectroscopy. The isolated grafted PANI-wool fiber was tested by conductivity measurements cyclic voltammetry, and IR spectroscopy to provide further evidence for chemical grafting.
