M.Schrödner: Synthesis, characterisation and forming of magnetoactive thermoplastic elastomers for applications in sensor and actuation technology
Description
Smart materials for multifunctional and functional integrated devices are increasingly important for research. They include hybrid materials, whose microscale interaction of components results in macroscopic magnetically controlled and mechanical compliant properties. Derived applications can be monolithic sensor actuator systems.
The considered project bridges the fields of material synthesis and technical implementation. Manufacturing technologies are strongly required to make the basic material fit for technical purposes. Shaping (semi-finished products, special forms) and the integration in industrial processes are crucial criteria, too.
Basing on the experiences with electroactive elastomers, the proposer plans the adaption of processes on magnetoactive thermoplastic elastomers. This includes the selection and testing of magnetic particles, the elastomer matrix and additional agents. Further characterization of the mechanical-dynamic and magnetic-dynamic properties as well as properties relevant for the production (particle dispersion, viscosity, etc.) is required. The early aim is the shaping of simple geometries (fibres, plates) and joining technologies (weaving or contacting on substrate) with the focus on manipulative sensory applications. In detail, investigations concern cilia structured functional surfaces and a tactile sensor mesh. The mechanic compliancy of both subjects is controlled magnetically and the integration of additional functionalities is possible.
