Effect of solvent on morphological properties of TiO x thin film

Abstract

Sol-gel preparation of amorphous titanium oxide (TiO x ) thin films with distinct morphological properties on the hydrophobic substrate was obtained by solution spin coating method. The TiO x thin films were deposited by three precursors using 2-methoxyethanol (2MOE), isopropanol (IPA) and mixture of 2MOE and hexane as solvents. We demonstrate evidence that the morphology of TiO x thin film is strongly related to the employment of dissimilar solvent. Among these three solvents, TiO x film obtained from 2MOE/hexane mixed solvent is a superior choice for the preparation of TiO x thin film on the hydrophobic substrate because of its smooth surface morphology.
