      abstract     = {Polymer brushes lead to small friction and wear and thus
                      hold great potential for industrial applications. However,
                      interdigitation of opposing brushes makes them prone to
                      damage. Here we report molecular dynamics simulations
                      revealing that immiscible brush systems can form slick
                      interfaces, in which interdigitation is eliminated and
                      dissipation strongly reduced. We test our findings with
                      friction force microscopy experiments on hydrophilic and
                      hydrophobic brush systems in both symmetric and asymmetric
                      setups. In the symmetric setup both brushes are chemically
                      alike, while the asymmetric system consists of two different
                      brushes that each prefer their own solvent. The trends
                      observed in the experimentally measured force traces and the
                      friction reduction are similar to the simulations and extend
                      to fully immersed contacts. These results reveal that two
                      immiscible brush systems in mechanical contact slide at a
                      fluid–fluid interface while having load-bearing ability.
                      This makes them ideal candidates for tribological
                      applications.},
