Graphene layers are produced by a variety of methods, such as chemical vapor deposition, spin and bar coating. These methods however have their limitations, such as not being able to process large substrates or sheets. Unlike CVD, spin and bar coating, ultrasonic spray technology is being used to spray graphene oxide onto large areas such as transparent conductive films (TCF). Ultrasonic spray is not to be confused with ultrasonic exfoliation, though the the energy used to exfoliate graphene is of importance when spraying graphene, which helps keep the material from agglomerating.
Applications for Graphene Coatings:
The number of potential uses for graphene is mind boggling. Graphene as an additive is an area of intense study utilizing ultrasonic technology for graphene coatings. Ultrasonic applications for processing graphene coatings onto a variety of substrates and applications include:
- Transparent conductive films
- Battery technology
- Solar Cells
- Sensors
- Flexible Electronics
- Transparent Electrodes
- Superhydrophobic Surfaces
- Protective Coatings
