Directly, edge-propylene graphitic nanoplatelets (EPGnPs) are made easily using only solid graphite and propylene gas via the mechanical chemistry without additional reactions. The edge-propylene functionalization is confirmed using various analytical techniques (e.g. FT-IR, EA, and TEM). The hydrophobic characteristic and outstanding properties of the EPGnPs make it suitable as a new reinforcing additive for polyolefins such as polypropylene (PP). In result, the tensile strength, yield strength, and Young's modulus of EPGnP/PP_5 nanocomposites are enhanced 90.5, 90.8, and 249.5%, respectively and also show the higher thermal stability compared with raw PP due to its remarkable properties as well as the enhanced affinity between PP and propylene-functional groups of the EPGnPs. Based on experimental results, the graphitic nanoplatelets (GnPs) with various functional groups, especially, hydrophobicity, offer a number of advantages (e.g., excellent compatibility, economy, and mass-production) for use as a filler to expand the applications of polyolefin composites.

直接使用固体石墨和丙烯气体通过机械化学轻松制造边缘丙烯石墨纳米片 (EPGnP)，无需额外反应。使用各种分析技术（例如FT-IR、EA 和 TEM）。EPGnP 的疏水特性和出色的性能使其适合作为聚烯烃（如聚丙烯 (PP)）的新型增强添加剂。结果，EPGnP/PP_5 纳米复合材料的拉伸强度、屈服强度和杨氏模量分别提高了 90.5%、90.8% 和 249.5%，并且由于其卓越的性能和增强的PP 和 EPGnP 的丙烯官能团之间的亲和力。基于实验结果，具有各种官能团，特别是疏水性的石墨纳米片（GnPs）作为填料提供了许多优势（例如良好的相容性、经济性和大规模生产），以扩大聚烯烃复合材料的应用.
