Nano -titanium dioxide decomposes bacteria to achieve antibacterial effects under the action of photocatalytic. Because the electronic structure of nano -titanium dioxide is a price zone full of TIO2 and an empty guide zone. In the water and air system, nano -titanium dioxide is under the sun, especially under ultraviolet rays. When the electronic energy reaches or exceeds its band gap Time. Electronics can be stimulated from the price zone to the guide zone. A series of reactions occur, which is adsorbed and dissolved in oxygen to capture electrons to form O2 ·. The generated supersonic anion free radicals are generated with most organic matter reactions (oxidation). At the same time, CO2 and H2O can be generated with organic objects in the bacteria; while the acupoints will be absorbed on the OH and H2O oxidation of OH and H2O on the surface of the TIO2 surface to · OH, · OH, which will have a strong oxidation ability. Atoms generate new free radicals, stimulate chain reactions, and eventually cause bacterial decomposition.

The sterilization effect of TIO2 lies in its quantum size effect. Although titanium pink powder (ordinary TiO2) also has a photocatalytic effect, it can also produce electronics and holes. It is difficult to play the effect of antibacterial effects, and TiO2, which reaches the degree of nano -level decentralization, has been migrated from the body to the surface. As long as the time of nanoseconds, picoseconds, and even femllo, the composite of photochemical electronics and cavities is magnified in nanoseconds. It can quickly move to the surface. Attack bacterial organisms and play a corresponding antibacterial effect.

TiO2 is widely used in textiles as a new type of inorganic antibacterial agent
The nano -level TIO2 particles have strong antibacterial properties under the light, and with the increase of antibacterial concentration and light time, the antibacterial rate is increased, and the antibacterial effect is significantly strengthened. It is feasible to treat the nano -TiO2 on the fabric with the soaking method, and the processed fabric has obvious antibacteriality, but the adhesive and dispersant need to be added to improve the combination of TIO2 and fabric. After adding adhesives and dispersing agents, the antibacteriality of the fabric has good water -resistant performance.

The advantages of nano -titanium dioxide antibacterial: safe and non -toxic for the human body, no irritation to the skin; strong antibacterial ability, wide range of antibacterial range; no odor,; long water resistance, long storage period; good thermal stability, non -changing color at high temperature, no decomposition, regardless of decomposition, regardless of decomposition, regardless of decomposition, regardless of decomposition. Do not volatilize, do not deteriorate; good instantability.
