As an efficient reinforcing additive to polystyrene (PS), edge-styrene grafted graphitic nanoplatelets (StGnPs) were prepared by the in-situ mechanochemical reaction between graphite and styrene. The resultant StGnPs exhibited excellent properties with good dispersibility in organic solvents. StGnP/PS nanocomposites were prepared via a facile solution process. Compared to pure PS, the StGnP/PS nanocomposites exhibited significantly enhanced mechanical properties (e.g., tensile strength, yield strength, Young’s modulus, and tensile toughness) along with improved thermal stability. The nanocomposites showed efficient load transfer from the PS matrix to the StGnPs because of the good dispersibility and compatibility of the StGnPs in the PS matrix. |
