This paper describes preparation of TiO2 –SiO2 coatings on cellulose substrates to provide self-cleaning properties. TiO2 and TiO2 –SiO2 coatings were compared. While the latter treatment provided the best protection of the cellulose from the damage facilitated by the titanium particle when exposed to sunlight, the former provided better photo-catalysis. Transmission (TEM) and scanning electron microscopy (SEM) were used for coatings morphology determination and zeta potential measurement were used for studying fibres surface properties.

The preparation and characterization of titanium (TiO2) coated self-cleaning cellulose materials starting from TiO2 P25 powder (Degussa, Germany) was studied. The aim of the research was to decrease high aggregation of TiO2 P25 nanoparticles. For this purpose cationic alkanediyl-?,?-bis-N-dodecyl-N, N'-dimethyl-ammonium bromide (Gemini) and anionic sodium dodecyl sulphate (SDS) surfactants were applied, with concentrations under their CMSs.
