1	Electrochemical characterization of nanostructured SnO2 and TiO2 forpotential application as dielectric materials in sulfonated-polyaniline based supercapacitors Ngqongwa, Lundi Vincent January 2010 (has links) <p>In this research project, nanostructured composites based on Tin dioxide (SnO2) and Titanium dioxide (TiO2) with poly-4-styrene sulfonic acid (PSSA) doped polyaniline (PANI) conducting polymer has been investigated based on their structural, electrical and electrochemical properties. The synthesis of conducting polymers and their metal oxide or composites have been carried out chemically or electrochemically according to methods modified from the literature. Layer-by-layer construction of nano-Metal Oxide/PSSA doped polyaniline composites were successfully constructed by electroanalytical methods on the surface of a glassy carbon working electrode (GCE).</p> Polyaniline Poly-4-styrene sulfonic acid Tin dioxide (SnO2) Titanium dioxide (TiO2) Supercapacitors Electrochemical impedance Cyclic voltammetry Electropolymerization Conducting polymers Galvanostatic charge-discharge Glassy carbon electrode.
