The dispersion behavior of chemically modified reduced graphene oxide (CRGO) has been investigated in five different solvents. Herein, we used cationic surfactant CTAB as a dispersing agent to prevent the agglomeration of graphene layers. The main role of the surfactant is to create dangling bonds on graphene layers and those help to exfoliate. In the physical process, ultra-sonication is used to break the π bonds whereas, in the chemical process, surfactant molecules occupy the space between the graphene layers. The dispersion behavior of CRGO in different liquid media has been observed for over a month. The chemically reduced graphene oxide was characterized by Transmission electron microscopy (TEM) analysis and current-voltage (I-V) measurement.
