High Performance Ultrasonicators for Graphene Exfoliation


To produce high-quality graphene nano-sheets, reliable high-performance ultrasonic equipment is required. Amplitude, pressure and temperature are crucial for reproducibility and consistent product quality. Hielscher Ultrasonics' ultrasonic processors are powerful and precisely controllable systems which allow for the exact setting of process parameters and continuous high-power ultrasound output. Hielscher Ultrasonics industrial ultrasonic processors can deliver very high amplitudes. Amplitudes of up to 200µm can be easily continuously run in 24/7 operation. For even higher amplitudes, customized ultrasonic sonotrodes are available. The robustness of Hielscher's ultrasonic equipment allows for 24/7 operation at heavy duty and in demanding environments. Our customers are satisfied by the outstanding robustness and reliability of Hielscher Ultrasonics systems. The installation in fields of heavy-duty applications, demanding environments, and 24/7 operation ensures efficient and economical processing. Ultrasonic process intensification reduces processing time and achieves better results, i.e. higher quality, higher yields, and innovative products. The table below indicates the approximate processing capacity of our ultrasonicators: The dispersion grade of graphene and graphene oxide is extremely important to use the full potential of graphene with its specific characteristics. Suppose graphene is not dispersed under controlled conditions. In that case, the polydispersity of graphene dispersion can lead to unpredictable or nonideal behaviour once it is incorporated into devices since the properties of graphene vary as a function of its structural parameters. Sonication is a proven treatment to weaken the interlayer forces and allows for accurate control of the important processing parameters.
