Summary: Friction coefficients and wear rates of PLA-stainless steel pair were investigated using four aprotic imidazolium and one bio-based protic ammonium ionic liquid (IL) lubricants. The ILs greatly reduced the friction coefficient and prevented wear in the rotational pin-on-disk test. The halogen-free protic ammonium IL exhibited the best performance in the linear reciprocating sliding test.

Summary: A new series of nanofluids based on graphene dispersed in 2-hydroxyethylammonium lactate (ML) ionic liquid was developed. The concentration of graphene and temperature showed significant effects on the viscoelastic behavior and conductivity of the nanofluids. The viscosity unexpectedly decreased with a low concentration of graphene, while shear thinning effects appeared with higher concentrations. The complex Burgers model was used to describe the creep-recovery behavior of the nanofluid with 1 wt% of graphene.

Summary: In this study, an oil-insoluble ionic liquid (IL) called [HMIM][TFSI] was encapsulated in poly(ethylene glycol dimethacrylate-butyl methacrylate copolymer) (poly(EGDM-c-BMA)) microshells using mini-emulsion polymerization. The microcapsules showed good dispersibility in a non-polar synthetic oil. Tribological experiments revealed that the microcapsules acted as a reservoir for the IL, reducing friction by releasing the IL at the sliding interface. X-ray photoelectron spectroscopy (XPS) measurements confirmed that the IL did not react chemically on steel surfaces, suggesting that it reduced friction by generating a solid-like, layered structure at sliding asperities.

Summary: In this study, three novel fatty acid anion-based ionic liquids showed similar tribological behavior as lubricants for various material pairs, including steel, aluminum alloy, bronze, cast iron, and tungsten carbide. The corrosion behavior of the ionic liquids was mainly observed on the bronze surface, while XPS analysis indicated low chemical interaction with the surfaces of the tested materials.

Summary: The wetting behavior of steel surfaces can be improved by treating them with different types and concentrations of RTILs, making them more wettable by water and non-polar liquids. The water contact angle decreases with time elapsed, while the contact angle for non-polar liquids remains relatively unchanged within a specific time frame. The surface free energy of RTIL-treated steel surfaces increases, making them more prone to wetting by liquids.

Summary: Electrochemical exfoliation of graphene is an environmentally friendly method for mass production. In this study, three ionic liquids (ILs) were used to exfoliate and functionalize graphene as a lubricant additive. The concentration of IL was found to affect the functionalization density of graphene, with higher concentrations resulting in higher densities. The tribological properties of the exfoliated graphene were influenced by the different anions present, with one particular IL showing the best performance, reducing the friction coefficient and wear volume by 32% and 39% respectively. The lubrication mechanism and structural evolution of the functionalized graphene were also examined, highlighting the formation of a tribo-film and disorder transformation as contributing factors. The simultaneous exfoliation and functionalization of graphene present a promising lubricant for industrial fabrication.
