Overview of Nano titanium dioxide (TiO₂) dispersion
Nano titanium dioxide (TiO₂) dispersion is a colloidal solution formed by uniformly dispersing nano-scale titanium dioxide particles in water or organic solvents. Nano titanium dioxide has attracted widespread attention due to its unique physical and chemical properties, such as high photocatalytic activity, excellent UV shielding performance, and good thermal stability and chemical stability. Nano titanium dioxide dispersion is prepared by a special process to ensure the uniform distribution and long-term stability of nanoparticles in the dispersion medium and avoid agglomeration between particles.
Specifications of Nano titanium dioxide (TiO₂) dispersion
1. High-efficiency photocatalysis: Nano titanium dioxide can be excited to generate electron-hole pairs under ultraviolet light, has strong redox ability, and can degrade harmful substances in the environment.
2.Ultraviolet absorption and scattering: Due to its wide-bandgap semiconductor properties, nano titanium dioxide can effectively absorb and scatter ultraviolet rays and is widely used in sunscreen products and anti-aging materials.
3.High transparency: It can maintain high transparency even at higher concentrations, which is suitable for application scenarios requiring high transparency.
4.Good biocompatibility: It is harmless to the human body and has certain antibacterial properties, suitable for fields such as medicine and food packaging.
5.Good stability: Through surface modification, long-term stable dispersion can be achieved in different media, and it is not easy to settle or coagulate.
