Abstract
A method of forming graphene flower is provided, which includes introducing a hydrocarbon gas and an assistance gas into transformer-coupled plasma equipment, and providing a medium-frequency electromagnetic wave to the hydrocarbon gas and the assistance gas by the transformer-coupled plasma equipment to dissociate the hydrocarbon gas, and the dissociated hydrocarbon gas is re-combined to form the graphene flower, wherein the hydrocarbon gas is dissociated at a ratio of greater than 95%.
Claims21
A method of forming a graphene flower, comprising:
