Tungsten oxide (WO3) composite film is a film structure composed of tungsten oxide and other materials. Such composite thin films can be prepared by different preparation methods, such as physical vapor deposition (PVD), chemical vapor deposition (CVD), and solution methods.
The composition and properties of the tungsten oxide composite film depend on the selected composite material. The following are several common tungsten oxide composite films and their applications:
Tungsten oxide-silicon dioxide (WO3-SiO2) composite film
Such composite films can be prepared by depositing tungsten oxide and silicon dioxide materials together. This composite film has good optical and electrical properties and can be used in optical coatings, optoelectronic devices, sensors and other fields.
Tungsten oxide-silicon nitride (WO3-Si3N4) composite film
This composite film is prepared by depositing silicon nitride material on the tungsten oxide film. They have excellent mechanical strength, thermal stability and chemical stability and can be used in applications such as anti-reflective coatings, thermal barrier coatings and anti-corrosion coatings.
Tungsten Oxide-Metal Composite Film
These composite films consist of metallic materials such as tungsten oxide and metals such as aluminum, titanium or copper. This composite film is often used in the preparation of barrier layers, transparent electrodes and battery materials.
The preparation method and properties of the tungsten oxide composite film will vary depending on the composite material used and the application field. Its preparation process and performance research usually requires knowledge related to related materials science and thin film technology.
