We consider a material to be soft when it easily and readily adapts to an external stress. Nevertheless, time-dependent and viscoelastic processes, as prominent in many polymer- and colloid-based materials, are important for the performance of a large number of materials. When taken into account properly, dynamic processes in complex fluids, solutions and melts can be exploited for novel adaptive and responsive systems.
The talk will summarize examples from our lab demonstrating the potential of dipolar nanoparticles and their tailored interaction with polymer matrices and external fields for the investigation of the quasi-static and frequency-dependent nanorheological properties of soft matter. The dynamic behavior of ferromagnetic hybrid structures can further be adopted for swimming objects that can be propelled by chemical fuel under very low Reynolds number conditions.
