Resumo

Graphene showing excellent physical and chemical properties, has led researchers to explore it. It is an allotrope of carbon nanomaterials, and could be used in many fields. Studies have shown that graphene could be used to replace carbon nanotubes in composites. It can enhance the physical properties of the composites such as compression strength, flexural strength etc. However, the hydrophobicity and strong van der Waals forces between graphene layers keep it often in agglomerated state. In order to make graphene widely used in composites, the preparation methods of homogeneous graphene suspensions are important. This paper reviews the methods been used in graphene dispersion, including mechanical methods, chemical modification, and the combination of them. We hope this paper will point a reasonable direction for graphene suspension.
