Titanium dioxide (TiO 2 ) films were deposited by the oxygen plasma-assisted reactive evaporation (OPARE) method. TiO 2 films with an anatase structure were formed when activated oxygen plasma was supplied to the substrate during deposition, whereas the films with a rutile structure were formed when nonactivated oxygen gas was supplied. These results were explained by the promotion of the oxidization of titanium atoms by the supply of activated oxygen plasma, because the anatase film is obtained under conditions where sufficient oxidization of titanium atoms is achieved, and the rutile film is formed under the conditions where insufficient oxidization occurs. These results indicate that oxygen plasma assist is an effective method for promoting oxidization and reducing the amount of oxygen gas used in this method. Both films deposited with or without plasma assist at temperatures greater than 250 C exhibited ultra-hydrophilicity. These films also showed definition methylene-blue (MB) decomposition photocatalytic performance indexes in the range from 7.8 -11.9 mmolÁl À1 Ámin À1 . The described results indicate that the TiO 2 films obtained by this method exhibit adequate performance for photocatalytic applications.

“…Very recent studies have discussed the application of nanosized TiO 2 in textile finishing, using the sol-gel technique, to impart effective protection against UV radiation and bacteria, stain resistance, deodorization, as well as self-cleaning because of its photocatalytic activity [6][7][8][9][10][11][12][13][14][15].…”

In this study, the effect of UV irradiation on mechanical properties of both natural and synthetic fabrics is investigated. Also the UV degradation of fabrics before and after TiO2 padding is studied. Cotton is used as natural fabric, and polyester, polypropylene, and polyamide were used as synthetic fabrics. After deposition with TiO2, prepared samples were irradiated by different dosage of UV light and the changes in fiber surface and the adhesion of nanoparticles is tested. The scanning electron microscopy, elemental analyses of Ti, and other methods were used. In some cases, the effect of stabilization of nanoparticles on fibers by UV light was realized. Reasons of this stabilization are the surface changes of polymer fibers-increase in surface roughness and oxidation of surface.

“…The decomposition performance index is defined as the slope of the Methylene Blue (MB) concentration changes for the UV irradiation time, generally used to estimate the organics decomposition performance [17]. The photocatalytic activities of the TiO 2 films were examined by photocomposition of MB with the concentration of 12 mmol/L in aqueous solution by UV light irradiation.…”
