Yellow tungsten oxide nanopowder may be used to produce nano-ceramic dispersion solution, which has excellent dispersibility. And this property is inseparable from its superhydrophobic property.
What superhydrophobic yellow tungsten oxide particle means? Due to the hydrophilicity of yellow tungsten oxide, water droplets dripping on the surface of the yellow tungsten oxide particles can rapidly penetrate into the sample. Under the combined action of the coarse structure of yellow tungsten oxide and octadecyltrichlorosilane, the modified yellow tungsten oxide particles exhibit excellent superhydrophobic properties, and the water droplets remain spherical on the surface of the particles. This phenomenon can be used as an important evidence for the successful modification of octadecyltrichlorosilane on the surface of yellow tungsten oxide particles. Furthermore, yellow tungsten oxide microspheres with a diameter ranging from 2μm to 3μm can be obtained by simple two-step acid deposition process. And these microspheres are composed of a lots of tiny nanosheet structures.
