Hexene-doping graphitic nanoplatelets (HxGNs), as a new filler, have extraordinary properties (e.g., hexene-functionalization, high specific surface areas, wedge-shaped pore, and so on) and interfacial interactions with hydrophobic polymers. Thus, HxGNs sufficiently increase the mechanical properties of poly(vinyl chloride) (PVC). HxGN@PVC_X nanocomposites can be prepared easily with a solution casting method because the HxGNs are well dispersed in THF. The tensile strength, Young’s modulus, toughness, and strain-to-failure of HxGN@PVC_5 nanocomposites increase by approximately 33.1, 27.3, 58.6, and 40.5%, respectively, compared with pure PVC. Especially, the low toughness of PVC, which hinders practical applications, has been greatly improved. The improved performance is from the outstanding properties of the HxGNs and the excellent interfacial interactions between the HxGNs and PVC chain. As a result, HxGNs as a filler act as a reinforcing agent and plasticizer for the PVC matrix.
