Design of Modern Equipment for Synthesis of Carbon Nanomaterials

The results of experimental studies aimed to multilayer graphene obtaining. Thermoexpanded graphite was used as a raw material. The technological regulations consisted of two main stages: obtaining a water-graphite suspension by cavitation method and grinding graphite globules on graphene plates using ultrasound or electrohydraulic impact according to Yutkin’s method. As a result of the experiment, a few layers of graphene were obtained, which is a pack of 10–20 graphene plates in each. CFD modeling of the cavitation process was performed. The analysis showed that the chosen geometry of the impeller blades, its speed, and angle of attack provides the necessary effect—cavitation and the necessary mixing throughout the volume. Graphite-graphene composites (GGC) have been obtained as a result of mechanical treatment of thermoexpanded graphite (TEG).
