Abstract

A lubricant formulation. The lubricant formulation includes a polyol-based base lubricant, an ionic liquid, and an organic nanoparticle. The ionic liquid is selected from the group consisting of trihexyltetradecylphosphonium bis(2-ethylhexyl)phosphate, trihexyl(tetradecyl)phosphonium bis-2,4,4-(trimethylpentyl)phosphinate, and trihexyl(tetradecyl)phosphonium bis(trifluoromethylsulfonyl)imide, or a combination thereof. The organic nanoparticle has a median particle size less than about 200 nm. The organic nanoparticle forms about 0.01 to about 5% by weight of the lubricant formulation. The ionic liquid forms about 0.5 to about 10% by weight of the lubricant formulation.
