Abstract

The oil-absorbing design of polytetrafluoroethylene (PTFE) fibers holds enormous potential for producing self-lubricating fabric composites with low coefficient of friction (COF) and high wear resistance but has not yet been realized. Current techniques rely on solid microcapsules to store liquid lubricants that generally do not exist for fiber materials. We demonstrate super-oil-absorbing PTFE fibers that combine mesoporous copper benzene-1,3,5-tricarboxylate (CuBTC) to contain abundant perfluoropolyether oil and levedopa/polyethyleneimine interface to firmly anchor CuBTC on their surface, leading to non-destructive mechanical properties and enhanced tribological characteristics due to solid-liquid synergistic lubrication between adsorption layer formed by perfluoropolyether oil, CuBTC fragments and PTFE transfer film. Notably, the COF and wear rate of as-made composites reduced by 20.1 % and 38.2 % than that of untreated composites. This work paves a new pathway to design microcapsules in self-lubricating fabric composites.

具有表面锚定介孔金属-有机骨架的超吸油聚四氟乙烯纤维增强自润滑织物复合材料的摩擦学性能

聚四氟乙烯（PTFE）纤维的吸油设计在生产低摩擦系数（COF）和高耐磨性的自润滑织物复合材料方面具有巨大的潜力，但尚未实现。目前的技术依靠固体微胶囊来储存液体润滑剂，而这种润滑剂通常不存在于纤维材料中。我们展示了超吸油PTFE纤维结合介孔铜苯-1,3,5-三羧酸盐（CuBTC），含有丰富的全氟聚醚油和左旋多巴/聚乙烯亚胺界面，使CuBTC牢固地锚定在其表面，通过全氟聚醚油、CuBTC碎片和PTFE转移膜形成的吸附层之间的固液协同润滑，从而获得非破坏性的机械性能和增强的摩擦学特性。与未处理的复合材料相比，复合材料的COF和磨损率分别降低了20.1%和38.2%。本研究为自润滑织物复合材料微胶囊的设计开辟了新的途径。

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
