- Facile Fabrication of γ‐Graphyne/Graphitic Carbon Nitride Quantum Dots Hybrids for Enhanced Tribological Properties of Epoxy Resin Composites Chunying Min Jiejie Huang Hongyu Liang Amna Siddique Zhiwei Xu Polymer Composites ABSTRACT The aggregation issues of two‐dimensional nanomaterials remain a barrier to improving the tribological properties of the polymer matrix. Herein, γ‐graphyne (γ‐GY)/graphitic carbon nitride quantum dots (CNQDs) hybrids were fabricated by the hydrothermal method and incorporated into epoxy resin (EP). CNQDs are uniformly anchored onto the surfaces of γ‐GY; the hybrids with multiscale structures are conducive to optimizing the interfacial compatibility with the EP. Compared with pure EP, γ‐GY/CNQDs/EP composites exhibited better thermal properties, with a 27.2% increase in tensile strength. Furthermore, the average friction coefficient and wear rate were decreased by 34% and 76.2%, respectively. The wear surfaces of γ‐GY/CNQDs/EP composites were analyzed via scanning electron microscopy (SEM) and energy‐dispersive spectroscopy (EDS) to reveal the synergistic lubrication mechanism between γ‐GY and CNQDs in the EP matrix. 10.1002/pc.70567 http://onlinelibrary.wiley.com/termsAndConditions#vor
