Functionalized graphene nanoplatelets from ball milling for 1 energy applications Xueliu 1 Fan, Dong Wook Chang2, Xuli Chen1, Jong-Beom Baek3 and Liming Dai Having a large surface area, high mechanical strength,
Silicon Carbide is an attractive material for a wide range of technical ceramics applications thanks to its specific properties, including chemical inertness at all temperatures, resistance to thermal shock and abrasion hardness and sinterability.
A wet ball milling route was used to synthesise SiC-graphene core-shell nanoparticles in situ from graphite and SiC nanoparticles. Graphite flakes were gradually exfoliated into fresh graphene nanosheets (GNSs) without significant defects, which is attributed to mechanical shearing and moderate impaction forces between graphite flakes, milling balls and SiC nanoparticles during the wet milling.
