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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
