Abstract
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.
