Analytical and Numerical Studies of End-Modified Polymer Brushes — •Dirk Romeis1,2 and Jens-Uwe Sommer1,21Leibniz-Institut für Polymerforschung Dresden e. V., Hohe Strasse 6, 01069 Dresden — 2Institut für Theoretische Physik, Technische Universität Dresden, 01062 Dresden

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.
