Unique advantages of ultrasonic coating for nanoparticles

Unique advantages of ultrasonic coating for nanoparticles. When conventional mixing devices and pumps are used for dispensing nanoparticles, the particles tend to agglomerate and separate from the liquid suspension.

Cheersonic developed custom solutions to liquid delivery of nano suspensions:
The liquid delivery systems employ discshaped piezoelectric transducers located inside a syringe plunger to convert highfrequency electrical energy into mechanical energy, which is transferred into the liquid suspension. A control module provides the high-frequency electrical input controlling power intensity and duration, depending on the liquid suspension characteristics. The resulting high-frequency and high-reflection vibrations created inside the syringe barrel effectively mix most slurries, dispersions, and suspensions to near-perfect homogenous blends within a few seconds. Further electrical impulses triggered automatically from the control module generate continuous vibrations, holding nanoparticles evenly dispersed in the suspension for several hours.

When conventional coating technologies (e.g. pressure spray coating, spinning disc coating and web printing technologies) are used to coat nanoparticles on substrates, their uniformity control is limited, and the amount of nano material that must be used is excessive and costly. Cheersonic ultrasonic spray nozzles uniformly and accurately coat very thin layer of nanoparticles on substrates of different shapes, forms and sizes. The ultrasonic spray nozzle continuously generates micronic droplets which carry within them identical concentration of nanoparticles. The nozzle imparts ultrasonic vibration into the liquid suspension, providing an agglomerate free system. By the time the liquid reaches the target, it evaporates and gently positions the nanoparticles with a transfer coefficient higher than 95% and practically no “bounce-back” associated with conventional coating technologies.
