Abstract

To expand the application of MOFs in self-lubricating composites, we synthesized metal organic frameworks (MOFs) MIL-88A tailored for oleylamine (Ole) adsorption, resulting in the Ole@MIL-88A composite with oleylamine adsorbed. This material was incorporated into epoxy resin (EP) to form EP/Ole@MIL-88A composites. The composites were firstly applied to axle sleeves for tribological evaluations. The tests revealed that the EP/10 wt% Ole@MIL-88A composite had the lowest COF (0.137), with a 65.9 % decrease compared to pure EP. The EP/8 wt% Ole@MIL-88A displayed the lowest wear depth, with a 68.4 % reduction compared to pure EP. This research signifies the initial application of MOF-based self-lubricating composites to mechanical components and engineering evaluations, laying the groundwork for their design in future industrial settings.

基于 MIL-88A 自润滑复合材料的油胺掺杂柔性金属有机框架的摩擦学应用

为了扩大 MOFs 在自润滑复合材料中的应用，我们合成了专门用于吸附油胺（Ole）的金属有机框架（MOFs）MIL-88A，得到了吸附油胺的 Ole@MIL-88A 复合材料。将这种材料与环氧树脂（EP）结合，形成 EP/Ole@MIL-88A 复合材料。首先将这些复合材料应用于车轴套筒进行摩擦学评估。测试表明，与纯 EP 相比，EP/10 wt% Ole@MIL-88A 复合材料的 COF（0.137）最低，下降了 65.9%。EP/8 wt% Ole@MIL-88A 的磨损深度最低，与纯 EP 相比降低了 68.4%。这项研究标志着基于 MOF 的自润滑复合材料在机械部件和工程评估中的初步应用，为其在未来工业环境中的设计奠定了基础。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
