Ultrasonic Graphene Granulation
Ultrasonic graphene granulation is a method of preparing graphene particles using ultrasonic energy. This method can effectively reduce the size of graphene, improve its dispersibility and application performance. The following are the basic steps and precautions for ultrasonic graphene granulation:
Steps:
- Graphene dispersion: Disperse graphene powder in an appropriate solvent to form a stable graphene suspension. Common solvents include water, acetone, anhydrous ethanol, etc.
- Ultrasonic treatment: Place graphene suspension into an ultrasonic reaction vessel and start the ultrasonic generator. The mechanical vibration and cavitation effects of ultrasound can disrupt the van der Waals forces between graphene layers, promoting the dispersion and granulation of graphene particles.
- Control parameters: Adjust the power, frequency, and processing time of ultrasonic waves to obtain the required graphene particle size and dispersion.
- Collection and post-processing: After ultrasonic treatment is completed, graphene particles are collected through methods such as centrifugation, filtration, or sedimentation. Further post-treatment may be required as needed, such as washing, drying, etc.
Matters needing attention:
- Graphene dispersion: Ensure that graphene is evenly dispersed in the solvent to achieve better granulation effect.
- Ultrasonic parameters: Reasonably select the power, frequency, and processing time of ultrasonic waves to avoid excessive fragmentation or aggregation of graphene.
- Post processing: Select appropriate methods for post-processing according to application requirements to optimize the performance of graphene particles.
- Safety and environmental protection: Always follow safety and environmental protection guidelines when using chemicals and conducting laboratory operations. Use appropriate personal protective equipment and ensure good laboratory ventilation.
Ultrasonic graphene granulation is an efficient and controllable method for preparing graphene particles with specific sizes and properties. This method has broad application prospects in fields such as new energy, composite materials, and conductive coatings.
