Dispersion for Graphene

Ultrasonic cavitation refers to the dynamic process of growth and collapse of micro-gas core cavitation bubbles in the liquid that vibrate under the action of sound waves, and when the sound pressure reaches a certain value.
When ultrasonic waves act on liquids, a large number of small bubbles can be generated. One reason is that partial tensile stress occurs in the liquid to form a negative pressure. The decrease in pressure makes the gas originally dissolved in the liquid supersaturate and escape from the liquid and become small bubbles. Another reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation.
Introduction：
The ultrasonic peeling of graphene is mainly due to the cavitation effect of ultrasonic waves. When the compressive stress wave propagates to the surface of the graphite body, the graphite body will reflect and generate tensile stress. Therefore, when countless tiny bubbles burst, the tensile stress between the graphite flakes will continue to increase until the graphene flakes are peeled off。
Advantage：
Dispersion time is short; dispersed particles are finer and more uniform; graphene is highly stable; energy saving and environmental protection.
