Homogeneous dispersion or full exfoliation of nanoparticles in polymer matrices is one of the most important factors to achieve high-performance and multifunctional polymer nanocomposites. In the past years, our research group is making efforts to realize homogeneous and stable dispersion as well as high orientation of carbon nanomaterials (e.g., graphene, carbon nanotubes) in aqueous and organic media as well as polymer matrices by using physical “hybridization” approach via effective combination (via π-π stacking, hydrogen bonding, etc) among different kinds of nanoscale building blocks (e.g., carbon nanomaterials). The graphene based nanohybrids thus constructed are prone to be homogeneously and stably dispersed in different media or polymer matrices, which are beneficial for fabricating high-performance carbon nanohybrids or polymer nanocomposites. In this presentation, some recent work progresses on achieving co-exfoliation or synergistic dispersion and stabilization of carbon nanomaterials in aqueous and organic media as well as structural construction of graphene based nanohybrids are discussed, and the potential applications of the prepared nanohybrids as electrode materials in high-performance supercapacitors are also demonstrated.
