  • Abstract

    Polyindole nanowires were synthesized by oxidative polymerization of indole using ammonium persulphate as oxidant. The structure of polyindole nanowires was confirmed by XRD, FT-IR spectroscopy. The FT-IR of polyindole nanowires shows a peak at1480 cm-1 which corresponds to the C-N stretching of the polymer. The morphology was studied by FESEM, which shows that the synthesized polymer has wire-like morphology. The electrochemical properties of the polyindole nanowires were studied by cyclic voltammetry. The synthesized polyindole nanowires were used to modify the glassy carbon electrode (GCE) and the modified GCE was studied in various background electrolytes in order to understand the oxidation and reduction behaviour of the polyindole nanowire.
