Method to effectively preparation dispersibility grapheme material is the important directions solving Graphene application.By at Graphene
Defect Edge and sheet surfaces introduce some specific functional groups and make its functionalization, be possible not only to give grapheme material special
Function, it is often more important that the introducing of these specific function groups can be greatly improved the uniformly dispersed of Graphene, reduce
Reunion between them；
At present grapheme material is except in addition to showing the electrical property of excellence in terms of electronic devices and components, the important use of another one
Way is to prepare high performance nano composite material, but owing to the chemical constitution of Graphene is highly stable, has between layers
Van der Waals force strongly, easily reunites so that Graphene is difficult to disperse in most solvents and matrix, greatly limits
Make the application of Graphene.
