Nano Cesium Tungsten Bronze Applied for Nano-ceramic Dispersion Solution

Nano cesium tungsten bronze, or nano grain size Cs0.33WO3, may be used to produce nano-ceramic dispersion solution, which may be applied to architectural glass to form a thin transparent heat-insulating film. And thus the building glass of such film may shield ultraviolet rays and near-infrared rays. In this regard, experts said that in general, inorganic nanoparticles are difficult to wet and disperse, but cesium tungsten bronze nanoparticles must have good dispersion stability to exhibit their own properties. And therefore it is very important to obtain a system with dispersion stability.

Here is the in-depth knowledge of the dispersion stability mechanism of cesium tungsten bronze nanoparticles. The stable dispersion of nanoparticles in a liquid medium generally involves three processes of wetting, dispersing, and dispersion stabilization. Wetting refers to the process in which the interface between the nanoparticles and the particles and between the particles and the air is replaced by the interface between the particles and the solvent. Dispersing is the process of deagglomerating agglomerated large-particle nanoparticles by external force to re-wet them. Dispersion stabilization means that the original particles or smaller agglomerates are shielded from van der Waals' gravitational force by electrostatic repulsion and steric repulsion, so that the particles no longer aggregate.
