The motivation of this work is to utilize the SFE for the direct preparation of highly pure TiO2 thin films without any subsequent thermal processing. Extraction with pure and modified scCO2 was tested and compared with PLE. Different types of liquid solvents (water, ethanol, acetone etc.) were used as scCO2 modifiers at concentrations from 0 to 30 mass %. The effect of extraction temperature (40–150 °C), pressure (10–65 MPa) and the volume (50–200 g) and flow rate (0.3–1.8 g/min) of solvents passed through the extractor on microstructure and purity of TiO2 thin films were examined.
