Fe3O4/石墨烯纳米复合材料的制.

Graphene is considered to be an ideal reinforcement because of its excellent properties. It is also prone to agglomeration, which reduces the properties of materials. In this paper, K2FeO4 was transformed to Fe3O4 by graphite and anchored on the graphite sheet by high energy ball milling in order to increase the shear force of grinding ball on graphite and then strip graphene from graphite. Dispersed Fe-based/graphene nanocomposites were obtained by controlling milling time. The composite powders were characterized by SEM, XRD and infrared spectroscopy. The results show that the Fe-based/graphene nanocomposites achieved by ball milling for 2 hours exhibited the best dispersibility and the number of graphene lamellae was low. [ABSTRACT FROM AUTHOR]
