eng Abstract:
In this work, the method using pure and modified supercritical carbon dioxide was tested to prepare a set of crystalline TiO2 thin films deposited on soda-lime glass. Precursor solution for TiO2 films was prepared by a templated sol-gel method in the reverse micelle environment. Simple approach or combination of several steps performed at different temperature (40-150 °C) and solvent composition was applied at pressure 30 MPa. Water, ethanol and water : ethanol (1:1) mixture were added into supercritical CO2 as modifiers at concentration 10-30 wt.%. The effect of extraction design on microstructure and purity of TiO2 thin films were examined.
