The present invention is highly dispersible, and an object highly conductive and oxidation resistance, namely to provide a graphene has high electrochemical stability.
To achieve the above object, the surface treatment graphene of the present invention is a surface treatment graphene compound or a neutralized salt thereof represented by the following general formula (1) in graphene is attached.
[Formula 1]
In (the general formula (1),
A: condensation C1-4, phenolic hydroxy groups benzene-based aromatic group having no R
1: a direct bond, a divalent hydrocarbon group having 1 to 12 carbon atoms or ether bond, ester bond, alcohol structure and divalent organic group R
2 having 1 to 12 carbon atoms having a structure selected from the group consisting of carbonyl
