The Effect of the Silicon Shell of Magnetic Microparticles on the Viscoelastic Properties of Magnetoactive Silicone Elastomers and Their Response to an External Magnetic Field

Magnetic microparticles with silicon shells of varying thickness have been obtained by modifying the surface of carbonyl iron. The structure and magnetic properties of the particles have been studied using scanning electron microscopy and vibrational magnetometry. The original and modified particles have been used as fillers to create magnetoactive elastomers based on polydimethylsiloxane. The concentration of magnetic particles in the magnetoactive elastomers varied from 40 to 80 wt
