Fe2O3–TiO2 coatings were successfully prepared on soda-lime silicate glass slide substrates using sol–gel method. Coating surface and morphology has been studied using X-ray diffractometer (RTG), scanning electron microscopy (SEM) and atomic force microscopy (AFM). Coatings were obtained using dip-coating method. To obtain sol Ti-alkoxide, Fe-chloride hexahydrate, ethylene glycol, acetic acid, isopropanol and glycerol were used. The obtained sol-gel films initially were dried 15 minutes in air at room temperature. Oxide films were obtained by heat treating the samples to 500° C for 1-5 hour. The present research is devoted to the studies of aging time and heat treatment effects on films hydrophobicity. X-ray results showed anatase, brookite, rutile and hematite crystalline phase formation. The purpose of this contribution was the development of iron oxide rich Fe2O3–TiO2 hydrophobic thin films depending on different preparation parameters. SEM and AFM observations show leaf-like structure formation on the sample surface.
