The development of nanomaterials based on conducting polymer-metal oxides for preservation and energy storage applications using various carbon materials is an important area of research. The combination of polymer and metal oxides provide the nanostructure materials with enhanced electrochemical properties [1–3]. The supercapacitor is often used with electrochemical reactions due to this storage device’s unique capabilities in terms of superior power, long stability cycles as well as fast charge and discharge rates. Electrochemical capacitors are widely employed in electronics, hybrid electric vehicles and in the energy sector [4–6] Conjugated polymers are well-known for their excellent electrical conductivities in an oxidized (doped) state. The recent development of processable conducting polymers has opened the way for large-scale industrial applications. Heteroaromatic molecules containing nitrogen have very interesting properties. Polyindole (PIN) has received significant attention in the past several years. Indole has both benzene and pyrrole rings, so PIN may have the properties of both poly (para phenylene) and polypyrrole.
