Preparation and Properties of TiO2 /Ag Antibacterial Agent
The TiO2/Ag nano-antibacterial material was prepared at low temperature using PEG-600 as reducing and stabilizer agent. The size and shape as well as the optics properties of the materials were characterized with TEM and UV-vis spectroscopy, and the antibacterial efficient was also investigated. The results showed that the average particle size of TiO2 was around 100 nm, the average particle size of nano-silver was around 20 nm, the nano-particles dispersed stably in solution, and the antibacterial efficient was 99.99 % as the concentration is 10 ppm, the minimum UV protective effect could be obtained as the concentration is 290 ppm.
