Titanium oxide nanoparticles (TiO2) are the most explored photocatalytic nanoparticles, and they have extensive application within catalysis, self cleaning, UV-shilding, optical filters, organic photovoltaic (OPV), organic and printed electronics, and many others.
We at Particular Materials synthesize nano TiO2 and we produce dispersions with excellent stability, monodispersity and fully disaggregated state.
Our Titanium oxide (TiO2) nanoparticles portfolio consist of particles with diameters ranging from 5 to 15 nanometers and find applications in several industries.
TiO2 nanoparticles with sizes below 20 nm display UV absorption behavior without light scattering and they are extensively employed as inorganic UV filter. The advantage of using monodisperse nanoparticles is better understood when we think that scattering phenomena are largely size dependent: a broad distribution of nanoparticles will increase the probability of light scattering phenomena, limiting the transparency of a coating.
In order to be able to take advantage of the various properties of Titanium Oxide (TiO2) nanoparticles, significant care needs to be taken in controlling size, monodispersity and crystalline structure.
We at Particular Materials synthesize nano TiO2 and we produce dispersions with excellent stability, monodispersity, crystalline purity and fully disaggregated state.
The TiO2 nanoparticles are available in two different sizes:
- 4.8 ± 0.9 nm
- 15.2 ± 3.5 nm
Typical concentration in water are, by weight (w/w%):
TiO2 can also be provided as nanopowder.
Related Applications and Industries
One of the primary uses of TiO2 nanoparticles is for its inherent UV-resistance, making it a crucial ingredient in various coatings and materials as UV screen.
Another key usage of titanium oxide nanoparticles is in the production of self-cleaning materials, such as self-cleaning glasses and ceramics.
The optical properties of titanium oxide nanoparticles makes it of value in the production of certain printing inks. Dispersibility and stability of the colloidal dispersion is of paramount importance.
Many cosmetics utilize titanium oxide nanoparticles for its unique antibacterial and optical properties. This includes moisturizers, beauty creams, whitening creams, vanishing creams, sunscreens, powdered make-up, skin rinses, and many other products.
Various organic substances degrade when exposed to titanium oxide nanoparticles, making it useful in certain decontamination efforts and in the treatment of sewage and organic chemical waste products. Due to its photo-catalytic properties, titanium oxide nanoparticles can serve as a key ingredient in various antibacterial and antiseptic compounds.
A peculiar characteristic of all nanoparticles is the high surface area to volume ratio, that allows a considerably higher binding capacity and excellent dispersibility of NPs in solutions.
