In this work, the influence of the substrate temperature on properties of cobalt oxide thin films has been reported. Cobalt oxide thin films were prepared by electrostatic spray deposition technique on glass substrate at different temperature of the substrate. The properties of cobalt oxide films were characterized by X-Ray diffraction (XRD), scanning electron microscope, Raman spectroscopy, UV-visible spectrophotometer, respectively. In additional, the crystalline structural parameters can be performed from XRD data. Phase transformation of cobalt oxide films due to different substrate temperature was observed. Moreover, the optical properties of films were depended on the quantity of phase transition in cobalt oxide film.

Titanium dioxide (TiO2) nanoparticles thin films were prepared by electrostatic spray deposition technique. The effect of the deposition times on properties of TiO2 films was investigated. The characteristics of TiO2 thin films were performed by X-ray diffraction, and Raman spectroscopy. In addition, the TiO2 nanoparticles thin film was deposited onto the interdigited electrodes to fabricate the humidity sensor device. The humidity adsorption and desorption properties of the sensor were studies. The sensing mechanism of the humidity device can be explained by complex impedance analysis.

In this work, cobalt oxide thin films were prepared by electrostatic spray deposition (ESD) technique. The influence of the substrate temperatures on properties of film was investigated. Phase transformation of cobalt oxide thin films due to the effect of different substrate temperature was also observed. Cyclic voltammetry was used to measure the performance of cobalt oxide supercapacitor. At higher substrate temperature, the cobalt oxide thin films exhibit the high specific capacitance due to the effect of phase transformation in cobalt oxide films.
