We investigated the environmentally friendly water lubrication by tethering polyelectrolytes on the substrates with sufficiently high grafting density, so-called polymer brushes. The hydrated brushes in aqueous media formed water lubrication layer to reduce friction coefficient without any organic surfactants and oils, which must be useful not only for artificial joints and bio-devices but also for roller bearing. Macroscopic tribological properties of polyelectrolyte brushes bearing ammonium salt, sulfonic acid, or phosphorylcholine unit were characterized by ball-on-plate type tribotester in the air, water, and salt solution sliding a glass ball on the surface under a loading of 0.49 N. The low friction coefficient below 0.02 was observed in polyelectrolyte brushes in water.
