| 中文摘要 | Four kinds of room temperature ionic liquids (RTILs), as a new kind of lubricant for micro/nano- electromechanical system, with the same imidazolium cation but carrying different anions including hexafluorophosphate, tetrafluoroborate, nitrate and perchlorate were synthesized and these nano-scale films were prepared on single-crystal silicon wafer by dip-coating method. Atomic force microscopy was used to examine themorphologies of thefilms and evaluate their nano-friction and nano-adhesion proper- ties. Chemical compositions of the films were characterized with a multi-functional X-ray Photoelectron Spectrometer. Micro-tribological properties of RTIL films were evaluated using a ball-on-plate micro- tribometer, and compared to that of perfluoropolyether. Results showthat 3-butyl-1-methyl-imidazolium hexafluorophosphate exhibited the best anti-wear ability in comparisonwith the other four lubricants, so the ionic liquid films could be used as a kind of novel lubricant for application in MEMS/NEMS. Friction- reduction, adhesion resistance and anti-wear properties of RTILs were closely related to their anions. For the friction at nano-scale, the surface energy of the lubricant played a significant role,while the durability and friction-reduction of IL films strongly depend on their anions at micro-scale. |
