Edge-propylene graphitic nanoplatelets (EPGnPs) are prepared via a mechanical chemistry with solid graphite and propylene gas as an efficient and economical additive for polypropylene (PP). Due to the remarkable dispersibility of EPGnPs in organic solvents (e.g., xylene), PP/EPGnP nanocomposites are made easily through the solution mixing method. PP/EPGnPs nanocomposites show far superior mechanical properties (e.g., tensile strength, yield strength, Young’s modulus and tensile toughness) and thermal stability to the raw PP. It is due to the remarkable properties of EPGnPs in itself as well as the enhanced affinity between PP and propylene-functional groups at the edge of EPGnPs. In results, EPGnPs will be a new candidate for a reinforcement to improve the polymer properties because of excellent properties, especially compatibility, economical and mass-production of graphitic nanoplatelets (GnPs). |
