We investigate the behavior of grafted polymers, where some of the polymers free ends are modified in size and interaction strength with the surrounding solvent. Recent simulation data [1] revealed remarkable localization effects of these end-groups in densely grafted brushes upon changing the solvent quality, respectively the temperature. Additionally, using the analytical self-consistent field approach for polymer brushes as provided in the limit of strongly stretched chains, we present a model to describe a mixed brush of hydrophobic and hydrophilic polymer chains.
