摘要: Abstract The applications of ionic liquids (ILs)/lamellar liquid crystals (LLCs) have great potential in nanotribology because they could be used where conventional oils not work. To clarify the lubricating mechanism, herein, ILs/LLCs lubricants were prepared by addition amphiphilic 1-alkyl-3-methylimidazolium hexafluorophosphate (CnmimPF6, n = 8, 12) into TritonX-100/n-C10H21OH/H2O LLCs with different concentration. influence alkyl chain lengths ILs on microstructures and tribological properties investigated. phase structure parameters presence CnmimPF6 analyzed via freeze-fracture transmission electron microscopy (FF-TEM), small-angle X-ray scattering (SAXS) technique, oscillating reciprocating friction wear tester. Compared without CnmimPF6, 4.5 wt% /LLCs can reduce sliding pairs. better property antiwear capability CnmimPF6/LLCs may attributed to increasing interlayer thickness d decreasing bilayer d0 microstructures. This work provides a understanding relationship between performances ILs/LLCs.
