Multifunctional hybrid nanocomposites with magnetically controlled reversible shape-memory effect.
Magneto-sensitivity and a thermo-sensitive reversible shape-memory effect have been successfully integrated into a hybrid nanocomposite, resulting in a magnetically controlled actuator. The complex requirements for gaining this multifunctionality are fulfilled by combining netpoints on the molecular and nano level in a polyesterurethane network prepared from hydroxyl group decorated magnetic nanoparticles, crystallizable star-shaped poly(ω-pentadecalactone) precursors, and a diisocyanate.
