Magnetorheological (MR) foam consisting of carbonyl iron particles (CIPs) embedded in an absorbent foam of matrix has great responsiveness towards magnetic field stimuli. Possessing such advantages, MR foam can be used as a controllable medium with manipulative properties, including rheological and sound absorption. In fact, changes in properties of MR foam are closely related to structural changes, which are influenced by various parameters, including the presence or absence of magnetic fields. However, previous studies reported limited findings on the mechanism behind the changes in the...

Magnetorheological elastomer (MRE) is widely known as a smart material owing to its excellent rheological properties that can be manipulated continuously, rapidly, and reversibly by applying an external magnetic field. MRE consists of magnetic particles that are embedded in a non-magnetic solid of elastomeric matrix. Carbonyl iron particles (CIPs) is widely used as favourable magnetic particles to be fabricated in an MRE due to high permeability, high saturation magnetization and low remnant magnetization. However, the use of CIPs in MRE devices subject to long-term exposure to severe...
