Electrochemical supercapacitor application of electroless surface polymerization of polyaniline nanostructures

초록

Electrochemical supercapacitive behaviour of polyaniline nanostructures, i.e., nanorods and nanospheres fabricated on aniline-primed conducting indium-tin oxide substrate via electroless surface polymerization using ammonium persulfate as initiator and selenious acid as efficient dopant is investigated. The self-assembled monolayer of urea derivative in presence of 3-(triethoxysilyl)-propyl isocyanate and aniline plays role of aniline-primed substrate. Polyaniline electrode composed of nanorods of excess surface area responsible for large redox reactions has shown 592 F g(-1) specific capacitance which is significantly greater than closely compact polyaniline nanospheres, i.e., 214 F g(-1).
