Title: Rheological Properties and Applications of Magnetorheological (MR) Materials
During the last few decades, magnetorheological (MR) materials have attracted a significant amount of attention for their enormous potential in engineering applications. MR materials are well known as smart materials family due to its rheological properties can be continuously, rapidly and reversibly changed by manipulating an external magnetic field. The capability to change tunable properties depends on the penetration values of the magnetic field inside the materials. MR materials are constructed of at least two different states of components, typically non-magnetic carrier or matrix, and micron-sized magnetizable particles. The micron-sized magnetic particles are having high permeability and saturation magnetization within non-magnetic carrier, and react to the magnetic field resulting in alteration of MR effect. However, rheological properties of MR materials are highly affected many parameters such as particle shape, composition, additives, type of medium, and particles weight of fraction. At such, the magneto-induced of MR properties are varies, thus, suitable in specific practical applications. Therefore, in this highlight, the influences of these parameters on the rheological properties of MR materials including MR fluid, MR elastomer, MR grease, and MR gel are reviewed. The application of MR materials in MR devices are also presented.
