Three typical surfactants: sodium dodecyl benzene sul- Surfactants fonate (SDBS), which is an anionic surfactant; tetradecyl dimethyl betaine (BS14), which is a zwitter ionic surfactant Hansen solubility parameters (HSPs) and cetylpyridinium chloride (CPC), which is a cation surfactant were used as the dispersant to functionalize the Dispersion reduced graphene oxide. The functionalization of reduced graphene oxide was characterized by Fourier transform Functionalization infrared (FTIR), Raman spectroscopy and X-ray diﬀraction (XRD). Surface morphology of diﬀerent reduced graphene oxide was studied by Field emission scanning electron microscopy (FESEM). Dynamic light scattering (DLS) was employed to explore the dispersion of reduced graphene oxide and functionalized reduced graphene oxide in 24 diﬀerent solvents. Furthermore, we reported the eﬀect of surface functionalization on the
