The nanocomposite electrodes were formed by depositing titanium dioxide onto FMWCNTs using reactive magnetron sputtering, thus providing a green roue for the formation of the binder-free composite electrode. It is shown that the electrochemical performance of the fabricated electrodes can be altered by tuning the thickness of the titanium dioxide overlayer. The integrated nanocomposite electrode showed an improved specific capacitance of 90 Fg-1 in two-electrode configuration. © 2016 IOP Publishing Ltd.CarbonCarbon nanotubesChemical vapor depositionComposite materialsElectrodesFabricationMagnetron sputteringMultiwalled carbon nanotubes (MWCN)NanocompositesNanotubesOxidesTitaniumTitanium dioxideYarnComposite electrodeElectrochemical performanceHybrid supercapacitorsNanocomposite electrodesReactive magnetron sputteringSpecific capacitanceSuper capacitorTwo electrodesElectrochemical electrodes
