    • Conductivity and tribological properties of IL-PANI/WS2 composite material in lithium complex grease
    Authors: Yanqiu, Xia; Yuanhui, Wang; Chenglong, Hu;  Advisor: -;  Co-Author: - (2022)

    An ionic liquid-polyaniline/tungsten disulfide (IL-PANI/WS2) composite was synthesized in 1-butyl-3-methylimidazole tetrafluoroborate (LB104) aqueous solution by in-situ polymerization and characterized by Fourier transform infrared spectroscopy. A current-carrying friction and wear tester was used to study the tribological properties of steel—steel and copper—copper friction pairs lubricated by an IL-PANI/WS2 lithium complex grease (LCG). After the experiment, scanning electron microscope was used to observe the surface morphology of the wear scar on the steel and copper plates, and X-ray photoelectron spectrometer was used to analyze the elemental composition of the wear scar surface. The results show that compared with greases containing IL-PANI and WS2, greases containing IL-PAN...
