摘要： The present invention relates to a method for preparing a functionalized graphene. The method for preparing a functionalized graphene according to the present invention can functionalize graphene by a simple method and does not use any other substance other than graphene and a salt containing a double bond, thereby enabling functionalization of graphene while exhibiting characteristics inherent to graphene.
