Hydrophilicity of TiO2 (titanium oxide) thinfilm
The photochemical properties of titanium dioxide make it can be used in many fields, such as air, water, and fluid purification. Photocatalysts doped with carbon or other heteroatoms can also be used in sealed spaces or regions with scattering light sources. When used in coatings on buildings, pedestrian slabs, concrete walls, or roof tiles, they can significantly increase the decomposition of air pollutants such as nitrogen oxides, aromatic hydrocarbons, and aldehydes. Besides, it is widely used in the production of sunscreen, non-toxic, harmless to the human body. Ultrafine titanium dioxide has excellent UV shielding and transparency. It is widely used in cosmetics, wood protection, food packaging plastics, durable household film, man-made fiber, and natural fiber, transparent coating. Because of its special optical effect in the metal flash coating, it has been paid attention to and applied in high-grade car paint. Principle of super hydrophilicity of TiO2 surface
