Abstract A series of graphene oxide composite lubricating films were fabricated in virtue of self-assembly technique driven by chemical bonds, which could strongly enhance interfacial interaction. The composite lubricating film Si-APS-GO-HOAF composed of GO and HFPO oligomer acid fluorides (HOAF) exhibited excellent tribological properties even immersed in 0.15 M NaCl solution for one month, attributing to strong interfacial interaction of chemical bonds and the synergistic effect of GO and HOAF. Furthermore, the outermost layer HOAF was partly adsorbed on the surface of the friction pair during the friction process and gradually formed a layer of transferred lubricating film. Surface analysis demonstrated that the formation of carbon oxide fragments and silicon oxides led to the damage of assembled layers, causing lubrication failure.

自组装氧化石墨烯复合薄膜摩擦学性能研究

摘要 利用化学键驱动的自组装技术制备了一系列氧化石墨烯复合润滑膜，可显着增强界面相互作用。由 GO 和 HFPO 寡聚酰氟 (HOAF) 组成的复合润滑膜 Si-APS-GO-HOAF 即使在 0.15 M NaCl 溶液中浸泡 1 个月也表现出优异的摩擦学性能，这归因于化学键的强界面相互作用和协同作用去和霍夫。此外，最外层HOAF在摩擦过程中部分吸附在摩擦副表面，逐渐形成一层转移润滑膜。表面分析表明，碳氧化物碎片和氧化硅的形成导致组装层的损坏，导致润滑失效。
