Multiscale carbon‐based hybrids are obtained by decorating either graphene oxide (GO) or carbon nanotubes (CNTs) on the surface of short carbon fibers (SCFs) via a facile layer‐by‐layer self‐assembly process. Hybridization of polytetrafluorethylene (PTFE) fibers and multiscale SCF hybrids is used to improve the tribological properties of polyphenylene sulfide (PPS)‐based composites. Results show that the presence of multiscale SCF hybrids can significantly enhance the compatibility between the host matrix and fillers. Scanning electron microscopy (SEM) observations reveal that the construction of an interlocking network structure formed by PTFE fiber and multiscale SCF hybrids is likely the contributing factor, which leads to better tribological properties of the resulting composites. The PPS/PTFE/SCF@GO20 composite exhibits the best tribological performance, with a friction coefficient of 0.165 and specific wear rate of 3.12 × 10−5 mm3 Nm−1, which are ≈73.6% and 99.6% lower than those of pure PPS, respectively.

聚四氟乙烯纤维和多尺度短碳纤维的杂交可显着提高聚苯硫醚的摩擦学性能

多尺度碳基杂化体是通过便捷的逐层自组装过程装饰短碳纤维(SCF)表面上的氧化石墨烯(GO)或碳纳米管(CNT)而获得的。聚四氟乙烯(PTFE)纤维与多尺度SCF杂化物的杂交可改善基于聚苯硫醚(PPS)的复合材料的摩擦学性能。结果表明,多尺度SCF杂种的存在可以显着增强基质与填料之间的相容性。扫描电子显微镜(SEM)的观察结果表明,由PTFE纤维和多尺度SCF杂化体形成的互锁网络结构的构建可能是促成因素,从而导致所得复合材料的摩擦学性能更好。-5  mm 3  Nm -1,分别比纯PPS低约73.6%和99.6%。
