چکیده
Tribological performance of polyalphaolefin 32, PAO, is investigated by adding two nanomaterials (graphene nanoplatelets, GnP, and hexagonal boron nitride nanoparticles, h-BN) an ionic liquid ([P 6,6,6,14 ][DEHP], IL1, [P 2,4,4,4 ][DEP], IL2, or ][(iC8) 2 PO ], IL3). Designed double hybrid nanodispersions are PAO/1 wt% ILX/0.05 GnP/0.1 h-BN (X = 1, 3). The best anti-friction behavior corresponds to PAO/IL3/GnP/h-BN (40% reduction compared that achieved with PAO). Anti-wear similar for the three nanodispersions. Roughness worn surface tested PAO higher than obtained each Tribo-film formation repair effect on surfaces due ILs nanoparticles revealed. Some positive synergies were found between IL GnP/h-BN as additives. • Three combined h-BN/GnP additives PAO32 analyzed. PAO/ILX/GnP/h-BN improve tribological single 40% friction 1 IL3 + 0.1 0.05 GnP added PAO32. 18% area IL1 Tribofilm formed and/or nanoadditives.

Towards Phosphorus Free Ionic Liquid Anti-Wear Lubricant Additives
The development of improved anti-wear additives would enable the use of lower viscosity oils that would lead to improved efficiency. Ionic liquids have the potential to be this type of new anti-wear additive. However, currently the best performing ionic liquids that are miscible in non-polar base oils, the phosphonium phosphates, contain phosphorus on both the cation and anion. Manufacturers ar...

متن کاملGraphene-analogues Boron Nitride nanosheets with ultrahigh ionic liquid uptake capacity as quasi-solid electrolytes
Inorganic nanoparticles are typically used as electrode materials in lithium batteries. However, to cope with the most challenge that solid electrolytes have low ionic conductivity at room or lower temperatures, here we show graphene-analogues boron nitride (g-BN) nanosheets absorbing a large quantity of ILs as a solid-like electrolyte. The layered g-BN nanosheets have very high specific surfac...

متن کاملAdsorption of choline benzoate ionic liquid on graphene, silicene, germanene and boron-nitride nanosheets: a DFT perspective.
The adsorption of choline benzoate ([CH][BE]) ionic liquid (IL) on the surface of different hexagonal nanosheets has been studied using Density Functional Theory (DFT) methods. For this, the interaction mechanism, binding energies and electronic structure of [CH][BE] ionic liquid on four types of nanosheets, i.e., graphene, silicene, germanene and boron-nitride, were estimated and compared. The...
