title: Melt blending in situ enhances the interaction between polystyrene and graphene through π-π stacking.
abstract: The effect of melt blending on the interaction between graphene and polystyrene (PS) matrix has been investigated in this paper. The interaction between graphene and PS was significantly enhanced by melt blending, which led to an increased amount of PS-functional graphene (PSFG) exhibiting good solubility in some solvents. The PS chains on PSFG could effectively prevent the graphene sheets from aggregating and the prepared PS/PSFG composites exhibited a homogeneous dispersion and an improved electrical property. The mechanism of melt blending on this enhanced interaction was attributed to the formation of π-π stacking during the melt blending. Moreover, the formation of chemical bonding during melt blending may have also enhanced the interaction.
