Nanowire Coatings Using Ultrasonic Spray

Ultrasonic Spray Systems for Metal Nanowire Deposition


Ultrasonic nozzles are used to spray silver or other metal nanowires, conductive inks or suspensions to create homogeneous, uniform nanowire coatings in energy, electronics, or other nanotechnology research applications. Sono-Tek nozzles are uniquely well suited to these spray applications because of the soft, controllable, non-clogging nature of the spray created. The atomized spray is easily targeted onto small or large areas.

Ultrasonic nozzle systems can be used for many emerging nanowire coating applications:

  • Chemical sensors
  • Flexible electronics
  • Semiconductor Transistors
  • Touch screen displays
  • Advanced battery applications
  • Catalyst materials
  • Thin film solar cells
  • Medical tissue scaffolding material

Sono-Tek ultrasonic spray systems have been proven successful for spraying nanowire coatings in advanced precision electronics research, and are used by some of the largest precision electronics manufacturers worldwide. Ultrasonic spray techniques are able to coat areas with more uniform dispersion of nanowire networks than other deposition methods. This uniformity results in better conductivity that can be achieved with thinner layers. When spraying nanosuspensions that are prone to agglomerating, our ultrasonic nozzles offer unique benefits in keeping particles evenly dispersed during coating.

CNT Drop Comparison

Sono-Tek ultrasonic nozzles operate by converting high frequency sound waves into mechanical vibrations, which atomize liquids into mathematically defined micron sized droplets. These droplets have a very tight drop distribution, and their size is dictated by the frequency at which the nozzle operates. Continuous vibrations of the nozzle disperse particles evenly in suspension during the coating process, creating homogeneous thin film layers of functional particles.

Benefits of Using Ultrasonic Spray to Deposit Nanowire Coatings:

  • De-agglomeration of particles in suspension
  • Choice of droplet size, depending on nozzle frequency
  • Cost effective spray equipment with full lab scale R&D and production systems
  • Soft, pressure-less ultrasonic spray will not damage delicate structures
  • Proven process spraying nanowire suspensions
  • Non-clogging, highly controllable spray
  • Fine line or wide area coatings
  • Capable of very low flow rates

Our ExactaCoat and FlexiCoat ultrasonic spray systems are both customizable full coating solutions, combining Sono-Tek ultrasonic nozzles with full programmable motion control, Windows-based software programming and recipe storage, and many advanced options available.

ExactaCoat and FlexiCoat Systems

Similar applications to nanowire spray deposition in which Sono-Tek nozzles have been proven for are carbon nanotubes or graphene spray deposition. The same benefits of deagglomeration and uniform dispersion of particles is seen in applications spraying silver nanowires.

Sono-Tek also offers the SonicSyringe, an ultrasonic dispersion syringe pump capable of mixing particles in nanosuspension in a matter of seconds and holding them evenly dispersed for several hours or more.
