Polymer brushes have been extensively studied as lubricious, bioinspired surfaces, and the majority of investigations has involved aqueous systems. While the environmental advantages of water-based lubrication is clear, there are many situations where it is impractical, either for reasons of temperature or viscosity. We have investigated the use of viscosifying agents, such as glycerol, for improving access to hydrodynamic lubrication at lower velocities, as well as the use of oil-compatible, 'grafting-from' brushes. In both cases, lubricating systems of practical interest have been obtained, but also a number of interesting fundamental aspects of brush lubrication have come to light.
