Ultrasonic Spray Coating for Nanomaterial
Ultrasonic nanomaterial coating system is particularly suitable for spraying nano suspensions, such as carbon nanotubes, nanowires, perovskites, graphene, etc.
In the process of ultrasonic spraying, while producing ultrasonic spray, vibration also has the characteristics of inhibiting the agglomeration or caking of nano materials. The uniformity of ultrasonic spraying reaches more than 95%, which plays a vital role in improving the spraying effect.
CNTs/Nanowires/Conductive Inks and Other Nanomaterial
Nanomaterials, such as carbon nanotubes, metal oxides, and nanoclay, are typically manufactured as dry materials, but due to their cohesiveness, they can clump or agglomerate when wet as sprayable coatings. Ultrasonic spraying technology can produce spray at the same time, vibration also has the characteristics of inhibiting agglomeration of nano materials, effectively improving the uniformity of spraying.
Nano suspensions successfully applied through ultrasonic spraying technology:
◆ Carbon nanotubes
◆ Nanowires and Graphene
◆ Magnesium oxide, indium tin oxide, cerium oxide, iron oxide, zinc oxide, cerium oxide, zirconium oxide, titanium and other metal oxides
Transparent conductive oxide (TCO) in touch screen applications.
◆ Drugs
Ultrasonic Spray Drying
After using ultrasonic atomization, the liquid solution is ultrasonically atomized into micron or submicron droplets. After further drying, dry powder with uniform particle size and high porosity can be obtained. Ultrasonic atomization is a key step in atomization granulation, which can form very small and evenly distributed particles and contribute to the long-term stability of nanoparticles.
Compared with traditional spray drying (centrifugal sprayer or air sprayer), ultrasonic spray drying can produce more uniform, smaller and better-shaped powder particles. It has broad application prospects in the fields of nanomaterials, fine chemicals, biomedicine, etc.
