Time–temperature superposition of silicone rubber embedded with irregular-shaped magnetic particles under different magnetic fields (opens in new tab)

The present work reports an investigation of the thermomechanical dynamic viscoelastic properties of a magnetorheological (MR) elastomer embedded with electrolytic iron particles (EIP, 40% wt, irregular shapes) in a silicone matrix. Unlike conventional MREs produced from spherical carbonyl iron particles, irregular flake-shaped EIPs offer greater particle–particle interactions and enhanced field sensitivity. The temperature rise from 30 to 70 °C significantly influences the matrix properties,...
