Abstract

In this study, fluorosilane-modified hollow mesoporous Diatom biosilica oil-carrying microcapsules (Oil@HMSNs/DE-F) were successfully synthesized using diatomite as hard-template, and dimethylsiloxane oil and hollow mesoporous silica as the core materials. Such microcapsules exhibited high oil-carrying capacity (41 %) and oil-carrying stability, which significantly higher than the Oil@DE-F microcapsules (33 %) (Comparison). Tribological tests showed that the Oil@HMSNs/DE-F composite coatings have excellent tribological properties and mechanical properties. Amazingly, 6 wt% Oil@HMSNs/DE-F epoxy composites coatings reduced the coefficient of friction by 79.9 % and the wear rate by 98.1 % compared to pure epoxy.

制备具有高载油能力和摩擦学特性的天然介孔硅藻生物二氧化硅微胶囊

本研究以硅藻土为硬模板，二甲基硅氧烷油和中空介孔二氧化硅为芯材，成功合成了氟硅烷改性中空硅藻生物载油微胶囊（Oil@HMSNs/DE-F）。这种微胶囊具有较高的载油量（41%）和载油稳定性，明显高于 Oil@DE-F 微胶囊（33%）（比较）。摩擦学测试表明，Oil@HMSNs/DE-F 复合涂层具有优异的摩擦学性能和机械性能。令人惊讶的是，与纯环氧树脂相比，6 wt% Oil@HMSNs/DE-F 环氧树脂复合涂层的摩擦系数降低了 79.9%，磨损率降低了 98.1%。

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.
