Sol-gel method is used to deposit each of the Titanium Dioxide (TiO 2 ) film coating layers to indicate the porosity and to see the thickness by each coating layers. The electrical properties were studied on the thickness variance. The surface morphologies of the prepared TiO 2 film were observed by using Field Emission Scanning Electron Microscopy (FESEM) to investigate the evolution of TiO 2 grains and surface morphology. The electrical properties were investigated by using current-voltage (I-V) measurement to study the electrical resistivity behavior hence the conductivity of the film. From this study, it is known that the coating layer affects the porosity and the thickness of TiO 2 film. Porosity of film was found to increase but the I-V was decreasing as the coating layer increased.
