Tailoring superelasticity of soft magnetic materials

摘要: Embedding magnetic colloidal particles in an elastic polymer matrix leads to smart soft materials that can reversibly be addressed from outside by external fields. We discover a pronounced nonlinear superelastic stress-strain behavior of such using numerical simulations. This results combination two stress-induced mechanisms: detachment mechanism embedded particle aggregates as well reorientation moments. The regime tuned or even switched on and off fields thus tailored during operation. Similarities the shape-memory alloys suggest analogous applications, with additional benefit reversible switchability higher biocompatibility materials.
