摘要
制备了两种对称结构的十二烷取代的饱和和不饱和咪唑基离子液体（[IM1212][Doss], [sIM1212][Doss]），并对其进行了表征和评价，作为PAO2的潜在纯润滑剂和润滑添加剂。结果表明，将咪唑环加氢得到饱和IL [sIM1212][Doss]不仅提高了其热稳定性（292 vs 253.2℃），而且提高了其在高温（175℃）下的抗摩擦、防磨损性能。值得注意的是，这两种添加剂都能溶解在合成油聚α -烯烃PAO2中，并表现出良好的摩擦学性能。润滑机理分析结果表明，润滑油与钢表面复杂摩擦反应形成的摩擦膜是其独特润滑性能的主要原因。
Dodecane-substituted saturated and unsaturated imidazolium-based ionic liquids: Investigated as potential lubricants and lubricating additives
Two dodecane-substituted saturated and unsaturated imidazolium-based ionic liquids (ILs) with symmetric structure ([IM1212][Doss], [sIM1212][Doss]) were prepared, characterized and evaluated as potential neat lubricants and lubricating additives for PAO2. The results suggested that hydrogenating the imidazolium ring to afford the saturated IL [sIM1212][Doss] not only improved its thermostability (292 vs 253.2°C), but also improved its anti-friction, wear protection properties at high temperature (175°C). Notably, both of them could be dissolved in the synthetic oil polyalphaolefin PAO2, and exhibited good tribological performances as lubricating additives. The lubricating mechanism analysis results indicated that the unique lubricating properties benefited from the tribofilm formed via complex tribological reactions between lubricants and steel surfaces.
期刊介绍：
The journal includes papers in the following areas:
– Simple organic liquids and mixtures
– Ionic liquids
– Surfactant solutions (including micelles and vesicles) and liquid interfaces
– Colloidal solutions and nanoparticles
– Thermotropic and lyotropic liquid crystals
– Ferrofluids
– Water, aqueous solutions and other hydrogen-bonded liquids
– Lubricants, polymer solutions and melts
– Molten metals and salts
– Phase transitions and critical phenomena in liquids and confined fluids
– Self assembly in complex liquids.– Biomolecules in solution
The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include:
– Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.)
– Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.)
– Light scattering (Rayleigh, Brillouin, PCS, etc.)
– Dielectric relaxation
– X-ray and neutron scattering and diffraction.
Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
