Ultrasonic Resonance Vibration For Graphene Aggregates Delamination Dispersion

Ultrasonic Resonance Vibration For Graphene Aggregates Delamination Dispersion

Description: 

Through the cavitation effect of ultrasonic waves, a large number of tiny bubbles are generated in the liquid, which continuously expand and collapse, generating high pressure and shear force, effectively destroying graphene aggregates. At the same time, ultrasound can cause resonance vibration in monolayer graphene, thereby reducing its van der Waals force and van der Waals force, promoting graphene delamination and dispersion. In practical operation, suitable solvents (such as water, ethanol, DMF, etc.) will be added to stabilize the dispersed graphene nanosheets.

Graphene is a two-dimensional carbon material with excellent mechanical, electrical, and thermal properties, and has broad application prospects in many fields.
