Abstract
Magnetoactive elastomers (MAEs) and magnetorheological elastomers (MREs) are widely explored for vibration damping, soft robotics, and biomimetic applications. Conventional ferromagnetic fillers such as iron (Fe) and its ferrimagnetic oxides (Fe<sub>3</sub>O<sub>4</sub>, Fe<sub>2</sub>O<sub>3</sub>) provide effective magnetic actuation but suffer from low corrosion resistance and limited biocompatibility. While poly-(dimethylsiloxane) (PDMS) offers excellent biocompatibility, its integration with bare Fe/Fe<sub>3</sub>O<sub>4</sub> particles remains challenging. In this work, we present a surface-engineering strategy to overcome these limitations by synthesizing Fe<sub>3</sub>O<sub>4</sub>@Ti core-shell particles via magnetron sputtering. The titanium shell improves chemical stability and surface compatibility, enabling better dispersion and performance within the PDMS matrix for magnetoactive applications.
