Ultrasonic Nozzle Systems for Spraying Nanosuspensions
Sono-Tek ultrasonic nozzles are uniquely suited to spraying nanosuspensions due to the inherent ultrasonic vibrations of the nozzle during atomization. Ultrasonic energy imparts continuous mechanical vibrations which serve to break apart agglomerated particles in suspension during the entire coating process. This is particularly beneficial where uniform dispersion of functional nanoparticles is required.
Nanomanufacturing processes benefit from the use of ultrasonic spray equipment for spraying nanosuspensions in several ways:
- The ability to spray ultra thin conductive layers with desired porosity characteristics.
- Targeted low velocity spray results in very little overspray of expensive materials.
- Ultrasonic spray systems are simpler and more cost effective than other deposition methods such as CVD or vapor deposition.
- Wide range of delivery rates, including very low flow rates are possible.
- Choice of drop size, down to 13 microns, depending upon nozzle frequency used.
- Programmable XYZ coating systems provide a full solution for your coating process, from R&D lab scale through production volume manufacturing.
- Fine line or wide area nanocoatings.
Examples of nanomaterials commonly sprayed:
- Carbon nanotubes
- Carbon catalyst inks containing precious metal oxides
- Transparent Conductive Oxides(TCO)
- Graphene and graphene oxide

Sono-Tek also offers unique liquid delivery systems for use with nanosuspensions, including the SonicSyringe ultrasonic dispersion syringe pump and the CSP Flow, a continuous ultrasonic dispersion syringe pump.
