Cover Story: Magnetic field-assisted control of magnetite location in a polymer composite is a promising strategy for flexible, conductive sensors. This study investigates the effect of static magnetic fields on thermoplastic elastomer (TPE) composites with magnetite and multi-walled carbon nanotubes (MWCNT). Composites with varying concentrations of magnetite and MWCNT were prepared by twin screw extrusion, and then compression moulded under a magnetic field. Applying a magnetic field to the melt at 190 °C enhanced magnetite/MWCNT interactions, substantially reducing electrical resistivity while maintaining thermal stability. Magnetite facilitated precise sensor positioning, demonstrating a scalable approach for enhancing sensor performance and positioning, with potential applications in flexible electronics.
