Graphene is a two-dimensional sheet of sp2-bonded carbon atoms with an extended honeycomb network. It has outstanding thermal, electronical, mechanical properties and performance-to-cost ratio compared to carbon nanotubes. In addition, because the graphene hinders polymer chain motion in polymer/graphene nanocomposites, it is effective to enhance heat resistance of polymers. However, the graphene is poorly dispersed in polymer matrixes and most solvents because of the strong interactions between the layers. Therefore, specific methods are required to disperse the graphene into the polymer matrixes. A melt template method, which forms a networking structure using silica or polymer beads, is a good candidate for the effective dispersion of the fillers. In this study, polystyrene (PS), a general-purpose thermoplastic plastic, was composited with graphene oxide (GO) via in-situ polymerization. Then the PS/GO composite plates were prepared using the melt template method. |
