Polymer-nanoparticle thin scaffolds with any-shape magnetic field gradients

Magnetic-assisted preparation and performance control of Fe3O4/PVDF gradient magnetic composites

“…Silva 21 created functional-level adhesive joints using polyurethane adhesive and iron microparticles, applying an appropriate magnetic field in the central region of the overlap area to form the functional-level adhesive joints. Mazur et al 22 studied the self-assembly of magnetic nanoparticles on a flat nanocomposite surface with hidden magnetic patterns and demonstrated that the application of multilayer stamped media and the presence of magnetic field gradients can attract and organize superparamagnetic iron oxide nanoparticles into predefined regions. Phuoc and Ong 23 prepared NiFeW thin films using composition-gradient deposition technique and characterized their static and dynamic magnetic properties at different temperatures.…”
