The response of adaptive multi-component polymer brushes to different applied patterned surfaces, as a function of the solvent quality, grafting density of the brushes, and for different sets of parameters related to the applied patterns, is studied in the framework of Molecular Dynamics simulations of a coarse-grained model with soft, non-bonded interactions and implicit solvent. The model is developed in order to address experimentally relevant, large invariant degrees of polymerization, and non-bonded interactions are expressed via a third-order (virial) expansion of the equation of state. The choice of interaction parameters mimics PAA-b-PS diblock copolymer brushes and PAA/PS mixed brushes. The role of the geometry and scale of the surface pattern is explored and related to the response of the inherent selected morphologies of the brushes without confinement.
