Ultrasonic Sonochemistry

Sonochemistry is the application of ultrasonic to chemical reactions and processes. The mechanism causing sonochemistry effects in liquids is the phenomenon of acoustic cavitation.
Cavitation, that is ” the formation, growth and implosive collapse of bubbles in the liquid. Cavitational collapse produces intense local heating (5000k), high pressures (1000atm), and enormous heating and cooling rates(>109k/sec)” and liquid jet streams (400km/h).

Ultrasonic perfect the graphene

The development of graphene industry demand high quality graphene urgently; (The traditional way of producing need to add more oxidant and reducing agent, while the ultrasonic exfoliation of graphite can greatly reduce the additive, greatly improve the purity and reduce the size of graphene.)

In recently years, with its excellent performance and a variety of potential applications, graphene been developed fast. At the same time, people need a lot of high quality and complete structure graphene. This requires to improve the existing preparation method, explore new preparation path. And the development of preparation method require better ultrasonic equipment too.

Ultrasonic

The principle of ultrasonic dispersion is make the ultrasound radiate in graphite oxide suspention the liquid promptly flow produce a large number of tiny air bubbles, these tiny bubbles formed in the negative pressure zone along the longitudinal ultrasonic radiation and grow continuously, and quickly closed in the positive pressure area, this effect is known as “cavitation” phenomenon, in this process, closed bubbles can form thousands of instantaneous high pressure. And the instantaneous high pressure will constantly and continuously shock the graphene oxide, make graphene oxide peeling off quickly.

Theoretical basis

Some authorities and universities from home and abroad have published many references mentioned advantages of ultrasonic dispersion of graphene suspensions

Graphene With Ultrasonic

Currently we use two step exfoliation can obtain high concentration graphene dispersion, second ultrasound in 30 hours reached the max conentration —- 20 mg/ml, the instantaneous concentration as high as 63 mg/ml.
After using various methods, the graphite expansion and the space between graphene sheets increases, the Vader waals forces between inter-layers reduce, at the same time use the liquid phase exfoliation can make graphene production rate greatly increased, and also can use water as solvent to obtain graphene, has a braod industrial prospect. Up to now, several companies use this way to achieve large production of graphene.
Through ultrasonic equipment, the surface of graphene reach 500 ~ 1000 m2 / g, thickness in 0.55 ~ 3.74 nm, the purity is more than 95 wt %, straight in: 0.5 3 microns, layer number less than 10.
