Spraying Graphene Coatings

Graphene is a single sheet of graphite, that is of hexagonally-arrayed carbon atoms, one atom thick, and is hence referred to as a "two-dimensional material". It is of significant interest for various applications. One application for graphene is transparent electrodes, which are useful for photovoltaic devices to provide a conductive top electrode that still allows a significant amount of light into a solar cell. Thus far, research has indicated graphene can carry up to 1000x the current of copper. Its electrical properties may also find use in displays, flexible electronics, microcomputers, and batteries.

Graphene is also being investigated as a lightweight and gas impermeable material, which may find applications in aircraft parts such as slides and rafts, potentially saving weight and hence fuel costs.

Graphene research is also being done in the biomedical field, for both medical imaging and tissue engineering applications.

Other graphene-based or graphene-similar materials, such as graphene oxide (thought to perhaps attract radioactive materials) and MXene materials (potentially for energy storage, catalysis, composites, etc.) are also of research and development interest.

Sonaer nebulizers and particle generators, and potentially high-temperature nozzles as well, can be used at various stages of graphene, graphene-related, or composite graphene material production via CVD and/or spray pyrolysis systems. Sonaer nozzles can be used to coat various subtrates with graphene, composite, or related coatings. Sonaer automated robotic coating systems can be used to produce such and other coatings reproducibly and efficiently. As scaled-up production and application of graphene and other nanomaterials is a key step towards their usage outside of the lab, Sonaer may also produce or assist in developing custom automated coating systems or "turn-key" CVD or spray pyrolysis units based on customer applications and needs, whether benchtop, prototyping, development, or production-level scale.

Graphene Coating Service

Sonaer dove tail spray shapper attaches to both wide and narrow spary atomizer nozzles for coating large areas with graphene. Solutions are delivered through the center orifice of the atomizer nozzle, where it is pulverized into small uniform droplets with a narraow distribuiton of particles. The dove tail attachment is also useful for coating very large areas by connecting several to make an array.

Rectangular spray shaper is useful where the substrate is square or rectangular. The customer supplies a small gas pressure, typically less then 5 PSI for spreading droplets over a wider area. Droplets with this type of attachment prevents the droplets from combining to make larger droplets by the unique design features.

Sonaer wide vortex spray attachment uses a small gas pressure to coat large areas with low volume of droplets. Droplets are dispersed over a wide area and provide a thin uniform coverage.
