Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite

open access: yesAdvanced Materials Technologies, Volume 10, Issue 13, July 8, 2025.
Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication

Triple‐Stimuli Responsive Soft Robots with Photo‐Programmable Ferriferous Oxide Particle Patterns

open access: yesAdvanced Science, Volume 12, Issue 18, May 15, 2025.
The in situ generation of Fe3O4 nanoparticles in polymer substrate is realized by combining photo‐reduction of Fe3+ to Fe2+ and hydrolytic reaction of the two ions. By spatiotemporal control of UV light irradiation, the distribution of Fe3O4 nanoparticle can be well controlled, which enables the composite with magnetic field, NIR light, and moisture ...
