There are six preparation methods of tungsten trioxide include hydrothermal synthesis method, precipitation method, sol-gel method, microemulsion method, gas-liquid reaction method and template method. Some special forms of tungsten trioxide powder can be prepared by different methods. It is due to the existence of this special structure and morphology that the synthesized tungsten trioxide has some new physicochemical properties.

Tungsten trioxide can be applied to the emulsion separation process in water pollution control, mainly to solve problems such as industrial oily wastewater and oil spill.

The super-hydrophobic coating using tungsten trioxide not only has UV resistance (UV or UV), but also has excellent self-cleaning ability, good mechanical properties and stable performance. One of the biggest defects of super-hydrophobic surfaces is poor mechanical properties.

Nowadays, research on the wettability of tungsten trioxide materials is not deep enough, although thanks to its unique optoelectronic properties, WO3 has been used in many fields such as photochromism, photocatalysis, electrochromism, sensors and information storage. These areas are also well-known applications of WO3, as many people know that tungsten trioxide is a common n-type semiconductor material. However, the lack of research on the wettability of WO3 will undoubtedly greatly limit the application of tungsten trioxide materials in practical industries. Therefore, the combination of tungsten trioxide material and wetting properties will have important theoretical and practical significance in the increasingly mature and application of WO3 preparation methods.
