A novel hybrid of carbon nanotube‐supported graphitic carbon nitride (g‐C3N4/CNT) was firstly fabricated via facile calcination method, and then filled into poly (phthalazinone ether sulfone ketone) (PPESK) to prepare self‐lubricating composite film. The microstructure and chemical composition of g‐C3N4/CNT hybrid were characterized, and its enhancement on the tribological properties of PPESK was investigated by comparing to pure PPESK and its composite films with g‐C3N4 or CNT only. Results showed that g‐C3N4 was in situ attached to CNT surface uniformly, which favored for improving the physical and chemical interfacial interaction between fillers and PPESK. Besides, by the incorporation of g‐C3N4/CNT, the hardness and elastic modulus of PPESK were improved by 15.05% and 41.75%, respectively. More importantly, PPESK‐g‐C3N4/CNT composite film showed the best tribological property among PPESK composite films. Its friction coefficient and wear rates were 65.5% and 84.1% lower than those of pure PPESK, as a result of good dispersion and interfacial action, as well as synergism between CNT and g‐C3N4. Based on the worn surface analysis, the enhancement mechanism of g‐C3N4/CNT was proposed.

碳纳米管负载的石墨氮化碳杂化剂增强聚苯并萘醌醚砜酮的摩擦学性能
首先通过简便的煅烧方法制备了碳纳米管支撑的石墨氮化碳（g‐C 3 N 4 / CNT）的新型杂化体，然后填充到聚（酞嗪酮醚砜酮）（PPESK）中以制备自润滑复合膜。表征了g‐C 3 N 4 / CNT杂化物的微观结构和化学组成，并通过与纯PPESK及其仅含g‐C 3 N 4或CNT的复合膜进行比较，研究了其对PPESK摩擦学性能的增强。结果表明，G-C 3 Ñ 4是原位均匀地附着在CNT表面，有利于改善填料与PPESK之间的物理和化学界面相互作用。此外，通过加入g-C 3 N 4 / CNT，PPESK的硬度和弹性模量分别提高了15.05％和41.75％。更重要的是，PPESK-g-C 3 N 4 / CNT复合膜在PPESK复合膜中表现出最好的摩擦学性能。由于良好的分散性和界面作用以及CNT与g-C 3 N 4之间的协同作用，其摩擦系数和磨损率比纯PPESK分别低65.5％和84.1％。基于磨损表面分析，g‐C 3 N的增强机理提出了4 / CNT。
