Uniform Thin Film Layer of Nano Materials Sprayed by Ultrasonic

The ultrasonic nano material coating system is particularly suitable for spraying nano suspensions, such as carbon nanotubes, nanowires, perovskites, graphene, etc. Due to the inherent ultrasonic vibration of the nozzle, energy will decompose the aggregated particles in the suspension, causing the liquid to undergo continuous mechanical vibration throughout the coating process without damaging the material. This is particularly advantageous when uniform dispersion of functional nanoparticles is required. In contrast, other spraying techniques cannot disperse clumps and are prone to clogging.

Nanomaterial coatings benefit from the use of ultrasonic spraying equipment to spray nanosuspensions in various ways:

• Capable of spraying ultra-thin conductive layers with the required electrical and transparent properties.
• Nanoparticles are evenly distributed on the substrate, maximizing the utilization of the material.
• Targeted low-speed spraying results in minimal overspray of expensive materials.
• Compared to other deposition methods such as dip coating, spin coating, and traditional spray coating, ultrasonic coating systems have greater flexibility, control, and cost-effectiveness.
• Choose droplet sizes as small as 13 microns based on the frequency of the nozzle used.
• The programmable XYZ coating system provides a complete solution for your coating process, from R&D laboratory scale to mass production.
• Fine lines or large-area nano coatings.

Common application examples of nanomaterials for spray coating:

• Deposition of CNTs (carbon nanotubes), nanowires, perovskite materials, and graphene in a uniform thin coating for alternative energy, electronics, semiconductor, or medical applications.
• Spraying catalyst inks such as carbon black and platinum solution in fuel cell manufacturing.
• Protection and reinforcement applications using graphene or carbon nanotubes.
• Various nanomaterials used for EMI shielding.
• Use conductive ink for nanoimprint printing of electronic products.
• Create a transparent conductive coating.
• Deposition of uniform nanowires or graphene films in advanced electronic applications.

The ultrasonic coating system is used to deposit nano layer coatings with uniform thickness on substrates of any width. Even on very wide widths, these very thin and highly uniform coatings can be formed, making ultrasonic spraying technology particularly suitable for many precision nanotechnology spraying applications.
