The optimized utilization of functional particles is very important for the practical applications ranging from catalysts, polishing media, and cooling fluids to cosmetics and sunscreens, which requires robust and cost-effective dispersion and surface functionalization routes. Additionally, nanopowders dispersion for chemicals, food, medicament, paint, and construction has become an important application in various fields. Because the nanoparticles have the volume and surface effects, it has outstanding qualities on light absorption, catalysis, magnetism, and so on.
However, the small size of particle is easily agglomerated and difficult to exhibit the advantages of nanoparticles. Therefore, how to improve the dispersion stability of nanoparticles in the liquid phase is a significant issue. TiO2 nanoparticles dispersions can be used for a variety of applications including self-cleaning, water treatment, antibacterial, and air purification due to their effective photocataytic activity. Furthermore, the TiO2-based hybrid nanomaterials are one of the most common nanocomposites, which are widely applied in medicine, lithium batteries, UV-screening, sensors, and hybrid solar cell materials. For these applications, TiO2 nanoparticles dispersion are generally coated on suitable substrates.
TiO2 Nanoparticles Dispersion is non-toxic and chemical properties are stable. It almost has no reaction with other material produce under normal temperature. It is a partial acid oxide. It has no reaction with oxygen, hydrogen sulfide, sulfur dioxide, carbon dioxide and ammonia and is not soluble in water, fatty acids, other organic acid and weak inorganic acid except for alkali and hot nitric acid. But, in some specific conditions, titanium dioxide can get reaction with some substance.
TiO2 Nanoparticles Dispersion is mostly used as white pigment because of its high diffraction index, strong light scattering, incident-light reflection capability and a high UV resistance that make TiO2 the standard pigment found in white dispersion paints with high hiding power. Since light scattering does not occur anymore in nanoscale particles, the white TiO2 pigments used are almost exclusively rutile modification particles with grain sizes in the micrometer range. These white pigments are not only found in paints and dyes but also in varnishes, plastics, paper and textiles.
Applications of TiO2 Nanoparticles Dispersion
Because of its unique properties, titanium dioxide is widely used and is well known in nanoscience and nanotechnology. TiO2 Nanoparticles Dispersion are one of the first materials to be used in nanotechnology products. However, the potential toxicity of titanium dioxide nanodispersion is a controversial subject. Many cosmetic companies use titanium dioxide nanoparticles. Because of its bright whiteness, it is used in products such as paints, coatings, papers, inks, toothpaste, face powder, and food coloring.
TiO2 Nanoparticles Dispersion are non-toxic and therefore are used in cosmetic products (sunscreens, lipsticks, body powder, soap, pearl essence pigments and tooth pastes) and also in special pharmaceutics. TiO2 is even used in food stuffs. TiO2 photo catalytic characteristics are greatly enhanced due to the advent of nanotechnology.
TiO2 Nanoparticles Dispersion dispersion is a well-known photo catalyst for water and air treatment as well as for catalytic production of gases. The general scheme for the photo catalytic destruction of organics begins with its excitation by supra band-gap photons and continues through redox reactions where OH-radicals, formed on the photo catalyst surface play a major role.
Pharmaceutical applications: Sterilization, restraining virus, TiO2 photo catalyst can destroy the membrane of cells, solid the proteins of viruses, restrain the virus activation and catching them. It kills bacteria’s up to 99.97%. TiO2 can kill coliform, green suppuration bacillus, golden grape coccus, mildew and suppuration fungus etc. The ability of sterilization can be tested through coliform and golden grape coccus.
