The group “Modeling of Polymer Materials” is engaged in application-oriented research of functional polymer materials on the mesoscopic and macroscopic scales. The group activities have two main directions. The first direction is devoted to studies of mechanical, rheological and electrical properties of filled polymer melts and networks. The main focus is on modeling of nonlinear effects under application of large oscillatory shear or steady-state shear. The second direction comprises analytical and numerical studies of stimuli-sensitive polymers such as photoresponsive azobenzene polymers and magneto-sensitive elastomers. Here the emphasis is put on prediction of stimuli-induced changes in a shape and the mechanical moduli of these smart materials.
