In this study, PANI and PANI/TiO2 composites were prepared as electrode materials for a supercapacitor application. Cyclic voltammetry (CV) was performed to investigate the supercapacity properties of these electrodes in an electrolyte solution of 6 M KOH. The PANI/TiO2 composites were polymerized by amount of various ratios through a simple in-situ method. The morphological properties of composites were analyzed by SEM and TEM method. The crystallinity of the composite and TiO2 particle size were identified using X-ray diffraction (XRD). In the electrochemical test, The electrode containing 10 wt% TiO2 content against aniline units showed the highest specific capacitance (626Fg^(-1)) and delivered a capacitance of 286 Fg^(-1) reversibly at a 100 mVs^(-1) rate. According to the surface morphology, the increased capacitance was related to the fact that nano-sized TiO2 particles (~6.5 nm) were uniformly connected for easy charge transfer and an enhanced surface area for capacitance reaction of TiO2 itself.
