Soft colloid suspensions in external flow fields — •Roland G. Winkler and Gerhard Gompper — ICS and IAS, Forschungszentrum Jülich, 52428 Jülich, Germany
Soft colloids, like linear polymers as well as more complex polymeric structures such as star polymers or polymer networks exhibit large conformational changes and an intriguing dynamics when exposed to, e.g., a shear flow .
The flow field leads to polymer stretching, associated with a shape change of the soft colloids, and alignment,
which depend on the specific structure of the particle. The particular structure even more determines the nonequilibrium dynamics. We will present simulation results of the nonequilibrium properties of such polymeric structures obtained by combining the multiparticle collision dynamics method, a mesoscale simulation approach for fluids , with molecular dynamics simulations for embedded polymeric objects. Moreover, the rheological characteristics of semidilute suspensions of linear  and star polymers  as well as end-functionalized semiflexible polymers  will be discussed.
