Copolymer Micelles as tunable Model System for Soft Colloids — •Gernot Rother, Joerg Stellbrink, Lutz Willner und Dieter Richter — Institut fuer Festkoerperforschung, Forschungszentrum Juelich

The structural response of ordered/disordered colloidal phases to applied external shear can be resolved using scattering techniques (DKD, U-SANS, SANS). For kinetically frozen PEP-PEO block copolymer micelles we expect, that the micellar interactions will vary from hard sphere to ultra soft on changing the block-copolymer composition. We study, how the several equilibrium structures of this model system are influenced by application of external shear.
