  We construct the complete structural phase diagram of polymer adsorption at
substrates with attractive stripe-like patterns in the parameter space spanned
by the adsorption affinity of the stripes and temperature. Results were
obtained by extensive generalized-ensemble Monte Carlo simulations of a generic
model for the hybrid organic-inorganic system. By comparing with adhesion
properties at homogeneous substrates, we find substantial differences in the
formation of adsorbed polymer structures if translational invariance at the
surface is broken by a regular pattern. Beside a more specific understanding of
polymer adsorption processes, our results are potentially relevant for the
design of macromolecular pattern recognition devices such as sensors.
