The objectives of the thesis: Study on materials fabrication technology; structural - photocatalytic properties of TiO2 material, and TiO2 as the nanostructured variant. On the basis of such material system, the systematic and quantitative study on hydrophilicity or, in other words, the study of surface energy of material systems under Exciation of UV light radiation. Further clarification of the correlation between photocatalytic activity, self-cleaning and hydrophobicity of TiO2 nanostructured materials. | Summary of the thesis: Study the fabrication and photocatalytic, hydrophilic properties of TiO2/SiO2 and TiO2/PEG thin films by sol-gel method
