Abstract
The present disclosure provides a method for dispersing graphene. The method includes the following steps: providing a graphene material and a graphene dispersant, wherein the graphene dispersant comprises aniline oligomer or aniline oligomer derivative, the aniline oligomer or aniline oligomer derivative is an electroactive polymer, and the aniline oligomer or aniline oligomer derivative is able to combine with the graphene material via π-π bond; and adding the graphene material and the graphene dispersant to a dispersing medium, making the aniline oligomer or aniline oligomer derivative combine with the graphene material via π-π bond, and dispersing the graphene material in the dispersing medium by the graphene dispersant.
