  We study the static and dynamic wetting of adaptive substrates using a
mesoscopic hydrodynamic model for a liquid droplet on a solid substrate covered
by a polymer brush. First, we show that on the macroscale Young's law still
holds for the equilibrium contact angle and that on the mesoscale a
Neumann-type law governs the shape of the wetting ridge. Following an analytic
and numeric assessment of the static profiles of droplet and wetting ridge, we
examine the dynamics of the wetting ridge for a liquid meniscus that is
advanced at constant speed. In other words, we consider an inverse
Landau-Levich case where a brush-covered plate is introduced into (and not
drawn from) a liquid bath. We find a characteristic stick-slip motion that
emerges when the dynamic contact angle of the stationary moving meniscus
decreases with increasing velocity, and relate the onset of slip to Gibbs'
inequality and to a cross-over in relevant time scales.
