摘要

甘油润滑剂由于抗菌性能不足而在工业应用中受到限制。本研究合成了一种功能化长链季铵盐离子液体 BTA-16-BTA。研究了 BTA-16-BTA 作为润滑油添加剂在不同含水量的甘油介质中的抗菌和摩擦学特性。结果表明，甘油介质的抗菌性能与 BTA-16-BTA 的添加量呈正相关。在最佳浓度为 1.5% 的 BTA-16-BTA 分散体中，观察到了极佳的减摩、抗磨和极压性能。当系统中加入 1%的水时，减摩和抗磨效果进一步增强。含有 BTA-16-BTA 的液体介质可以抑制大肠杆菌的生长，这表明 BTA-16-BTA 具有抗菌特性。

Lubrication and Antibacterial Performance and Mechanism of Functionalized Ionic Liquids in Glycerol Media with Different Water Contents

Glycerol lubricants face limitations in industrial applications due to their inadequate antimicrobial properties. In this study, a functionalized long-chain quaternary ammonium salt ionic liquid, BTA-16-BTA, was synthesized. The antimicrobial and tribological properties of BTA-16-BTA as a lubricant additive in glycerol media with different water contents were investigated. The results show that the antimicrobial performance of the glycerol medium is positively correlated with the amount of BTA-16-BTA added. At the optimal concentration of 1.5% BTA-16-BTA dispersion, excellent friction-reducing, anti-wear, and extreme pressure properties were observed. The friction-reducing and anti-wear effects were further enhanced when 1% water was added to the system. The liquid medium containing BTA-16-BTA can inhibit the growth of Escherichia coli, indicating that BTA-16-BTA possesses antimicrobial properties.

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.
