Dispersion of sp2 carbon materials such as carbon nanotubes (CNTs) and graphene in polymer matrices is considered to be essential for effectively utilizing the material in its primary structure. A great number of literatures have focused on the chemical modifications on the nanomaterials' surface through covalent bonding reactions; however, the methods are gener ally disadvantageous because of the possible disruption of the p-surface conjugation and the decrease of electric, opti cal, and thermal properties. Other methods of using poly meric dispersants for non-covalent bonding interaction with the target materials could also reach a homogeneous disper sion while maintaining the intrinsic characteristics without disrupting the covalent bonds of the materials. This review covers both methods of covalent and non-covalent interac tions with the p-surface of sp2 carbons including CNT and graphene, but emphasizing on the new developments of poly meric dispersants for achieving dispersion homogeneity and stability. In addition, the homogeneous dispersion could be the precursors for hybridizing metal nanoparticles (NPs) such as Ag and Pt to produce hybrid materials. These dispersion methods are further applied for maximizing the performances of the NP interaction with the fundamental graphene platelets. The fine dispersion of graphene in primary platelet units and their hybridizations with NPs have a myriad of applications for fabricating devices with advanced properties of electric conductivity, heat dissipation, and catalyst in dye-sensitized solar cell. ? 2016 by Taylor & Francis Group, LLC.
