Graphene nanocomposite materials are highly desirable in material sciences due to their extremely enhanced electrical, thermal and mechanical properties in many applications, but the manufacture of graphene nanocomposite materials has been very limited because of the low dispersibility of graphene oxide in organic solvents. In this respect, many studies have been carried out to enhance dispersion properties of graphene oxide (GO) for better processability. Among them, chemical modification to oxygen functional groups of GO is a simple route to improve dispersion properties of GO without causing any contaminations or structure deformations. In this study, we prepared polyetheramine functionalized GO, which was proved to have much enhanced dispersion properties in organic solvents as well as in water. The dispersion properties of GO and functionalized GO were discussed in detail by concentrations, zeta potentials and UV/Vis spectroscopy. |
