Sažetak
Nanostructured titania (TiO2) films were deposited on the borosilicate glass substrate by sol-gel process using dip-coating method. For the preparation of TiO2 sols, the following components were used: titanium (IV) isopropoxide as the titanium precursor, ethanol as a solvent, acetic acid as a catalyst, acetylacetone for peptization, distilled water for gelation. Starting TiO2 solutions were prepared with and without the addition of polyethylene glycol (PEG) as organic/polymer additive. The surface morphology and the nanoscale roughness of TiO2 films were studied using the atomic force microscopy (AFM). AFM analysis confirmed the presence of nano-structured sol-gel titania films on the glass substrate. Roughness parameters (Ra, Rmax, Rq, Rz and Zmax) of a sol-gel TiO2 film with the addition of PEG are higher than the values for the sol-gel TiO2 film without the addition of PEG.
