Function and Application of TiO2 Nanoparticles

Nano-titanium dioxide is a white loose powder with strong UV shielding effect, good dispersion and weather resistance. It can be used in cosmetics, functional fibers, plastics, coatings, paints, etc., as an ultraviolet shielding agent to prevent ultraviolet rays. It can also be used in high-end automotive topcoats, with a corner effect.


 The wide application of TiO2 nanoparticles mainly concentrates on:


1. Cosmetics


Nano-titanium dioxide is transparent, so it has many excellent characteristics and functions that ordinary cosmetic raw materials do not have in terms of blocking ultraviolet rays, transmitting visible light and safety. Nano-titanium dioxide can not only scatter ultraviolet rays (wavelength 200nm-400nm), but also absorb ultraviolet rays, so its ability to shield ultraviolet rays is extremely strong. It can be used as an excellent sunscreen agent and used to make sunscreen cosmetics. And because nano-titanium dioxide is transparent, it can be used to make a transparent skin care cream. This kind of skin care cream has a delicate cream body and a natural skin feel.


2. Antibacterial agent


Nano-titanium dioxide inorganic composition, non-toxic, odorless, non-irritating, good thermal stability and heat resistance, non-burning, and itself is white. Therefore, the application of tio2 nanoparticles is very popular in the antibacterial industry.


3. Solar battery raw materials


Because nano-titanium dioxide has excellent high-rate performance and cycle stability, fast charge-discharge performance and high capacity, and good reversibility of deintercalation of lithium, the application of nano-titanium dioxide in the field of lithium batteries has very good prospects.


4. Textile products 


Nano-titanium dioxide T25F is used in the textile sizing agent. Through the perfect combination with starch, it can improve the comprehensive weaving performance of the yarn, reduce the amount of PVA and cost of the sizing agent, and improve the benefit of sizing. It also solves many problems of PVA slurry, such as difficult desizing and environmental pollution. Nano-titanium dioxide in the yarn mainly replaces PVA, plays the role of smoothing hairiness, filling in gaps and lubricating.
