abstract = {It was found recently that two polymer brushes in a
tribological contact do not interdigitate when each polymer
brush has its own preferred solvent, leading to low friction
and low wear rates. Here, we demonstrate, using molecular
dynamics simulations, that mutually miscible and fully
solvated brush systems do not significantly overlap either
if the radii of curvature of the surfaces, to which the
brushes are grafted, are sufficiently small. The brushes
achieve this by bending away from the center of the contact,
while they bend toward the center of the capillary when
being only partially solvated. For the fully solvated
brushes, immiscible systems also show smaller friction than
miscible systems, although the friction reduction is less
than for partially solvated brushes.},
