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. |

![]() DOVE TAIL SPRAY SHAPER FOR GRAPHENE COATINGS |
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. |
![]() FLAT SPRAY SHAPER FOR COATNG LARGE AREAS WITH GRAPHENE |
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. |
![]() GAS ASSISTED SPRAY ATTACHMENT |
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. |
