To incorporate graphene into composites, the graphene must be dispersed/exfoliated as single nano-sheets uniformly into the formulation. The higher the grade of deagglomeration, the better the extraordinary material properties are exploited.
Ultrasonic dispersion enables for a superior particle distribution and dispersion stability – even when formulating at high concentrations and viscosities.
Ultrasonic processing of graphene gives outstanding dispersion qualities and excels conventional mixing methods by far.
In order to lend composites the outstanding material characteristics of graphene such as strength, graphene must be dispersed into a matrix or applied as a thin-film coating onto a substrate. Agglomeration, sedimentation, and the dispersion into a matrix (or particle distribution on the substrate, respectively) are important factors that influence the resulting material’s properties.
Due to its hydrophobic nature, the preparation of a stable and highly concentrated graphene dispersion without surfactants or dispersants is a challenging task. To overcome the van der Waals forces, strong shear forces generated by ultrasonic cavitation are the most sophisticated method to prepare stable dispersions.
Graphene with a high electric conductivity (712 S·m-1), good dispersity and high concentration can be easily prepared using an ultrasonic disperser, such as UIP2000hdT or UIP4000. Sonication allows to prepare a stable graphene dispersion at low process temperature of approx. 65°C.

RPS-SONIC Ultrasonics offers high-power ultrasonic systems for the exfoliation and dispersion of bulk-layered graphene and graphite into mono-, bi- and few-layered graphene. Reliable ultrasonic processors and sophisticated reactors deliver the required power, process conditions as well as precise control, so that the ultrasonic process results can be tuned exactly to the desired process goals.
One of the most important process parameters is the ultrasonic amplitude (the vibrational displacement at the ultrasonic horn). RPS-SONIC’s industrial ultrasonic systems are built to deliver very high amplitudes. Amplitudes of up to 200µm can be easily continuously run in 24/7 operation. For even higher amplitudes, Hielscher offers customized ultrasonic probes. All our ultrasonic processors can be exactly adjusted to the required process conditions and easily monitored via the built-in software. This ensures highest reliability, consistent quality and reproducible results. The robustness of RPS-SONIC’s ultrasonic equipment allows for 24/7 operation at heavy duty and in demanding environments. This makes sonication the preferred production technology for the large-scale preparation of mono- and few-layered graphene nanosheets.
