| description | Magnetodielectric properties of prepared ordered microstructured polydimethylsiloxane-based magnetorheological elastomer with the Fe<sub>3</sub>O<sub>4</sub>@rGO (Fe<sub>3</sub>O<sub>4</sub>@rGO/PDMS-MRE) were investigated to expand the application of magnetorheological elastomer (MRE) in magnetic sensing fields by improving the magnetodielectric effect. Five types of Fe<sub>3</sub>O<sub>4</sub>@rGO electromagnetic biphasic composite particles were synthesized by the solvothermal method, and their characterization and magnetic properties were also tested. Microstructurally ordered Fe<sub>3</sub>O<sub>4</sub>@rGO/PDMS-MRE samples with different Fe<sub>3</sub>O<sub>4</sub>@rGO concentrations were obtained through the magnetic field orientation technique, an experimental platform for magnetodielectric properties was built, and the relative permittivity of the samples was tested under magnetic flux density from 0 to 500 mT. The results show when the ratio of modified Fe<sub>3</sub>O<sub>4</sub> to GO reaches 10:1, the Fe<sub>3</sub>O<sub>4</sub>@rGO composite particles exhibit uniform distribution with a flaky structure and strong magnetic properties and have the best bonding effect of composite particles. The relative permittivity of Fe<sub>3</sub>O<sub>4</sub>@rGO/PDMS-MRE increases with the rise of Fe<sub>3</sub>O<sub>4</sub>@rGO concentration and applied magnetic flux density. The relative permittivity of Fe<sub>3</sub>O<sub>4</sub>@rGO/PDMS-MRE with Fe<sub>3</sub>O<sub>4</sub>@rGO concentration of 60 wt% reaches 12.934 under the action of 500 mT magnetic flux density, and the magnetodielectric effect is as high as 92.4%. A reasonable mechanism for improving the magnetodielectric effect of ordered microstructured Fe<sub>3</sub>O<sub>4</sub>@rGO/PDMS-MRE is proposed. |
