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.
磁敏性和热致形状记忆效应已成功集成到混合纳米复合材料中，从而产生了一种磁控致动器。通过在由羟基修饰的磁性纳米粒子、可结晶星形聚（ω-十五内酯）前体和二异氰酸酯制备的聚酯聚氨酯网络中，在分子和纳米水平上结合网络点，满足了获得这种多功能性的复杂要求。
