An alternative method of synthesizing ZnO-TiO 2 nanorods is through route precipitation and sintering at 600 C. In this study, the introduction of Ti into Zn in the molar ratio Ti:Zn (1:3) produced a composite ZnO-Low TiO 2 (ZnO-LTiO 2 ) while 1:1 produced ZnO-High TiO 2 (ZnO-HTiO 2 ). The effect of the Ti introduced on the antibacterial properties of ZnO-TiO 2 nanorods was investigated with the product structure characterized by XRD and the optimal intensity at 2θ: 31.72 , 34.37 , 36.19 showed a Wurzite structure and a crystal size of 35.8-41.5 nm. The average pore diameters for ZnO-LTiO 2 and ZnO-HTiO 2 were around 5.159 nm and 6.828 nm while the surface areas were 15.692 m 2 /g and 15.421 m 2 /g respectively. The anti-bacterial textile fiber construction was prepared using dip-spin coating with the application of an adipic acid crosslinker for 6 h and stable coating up to 10 times washing. The improvement of Pseudomonas aeruginosa (Pa) antibacterial properties in the textiles with coating had an inhibition zone of 20.5-25.0 mm and 16.2 mm without the coating. The elements of the cotton fiber construction include C at 54.60%, O at 40.89%, Ti at 0.81% and Zn at 2.60% while the TG-DTA analysis conducted showed an increase in the heat stability of the textile fibers to a temperature of 400 C, after which the textiles were modified by coating ZnO-TiO 2 nanorods. The findings of this research could be successfully applied to improve the antibacterial properties of textiles.

A series of titania thin films was prepared by chemical bath deposition (CBD) of TiCl 3 on indium tin oxside (ITO) glass at room temperature, followed by calcinations at 500°C for 4 hours. The effect of cyclic deposition on phase composition, microstructure and electrical resistivity of TiO 2 thin films was characterised using X-ray diffraction, scanning electron microscopy and four-point probe respectively. Results showed that TiO 2 films produced by single deposition cycle were amorphous. In contrast, those produced by 5 and 6 deposition cycles were partly amorphous and partly crystalline with the formation of rutile. Both the film thickness and electrical resistivity increased with an increase in the number of deposition cycles.
