Recent Progress on Magnetorheological Solids: Materials, Fabrication, Testing, and Applications

Abstract

Magnetorheological (MR) materials are classified as smart materials due to their responsiveness to external magnetic stimuli. Intensive research on MR materials has led to broad applications in several potential fields. A solid carrier matrix state called MR elastomer with its exceptional magnetic responsive feature is obtained by merging magnetizable particles within an elastomeric polymer. This integration results in outstanding characteristics on the rheological performances. Special prominence is given to the understanding of the base materials and fabrication as well as the functional behavior through various characterization methods. Broad applications of MREs are also explored to provide a profound market picture and to motivate researchers to develop novel technology.

Influence of the geometry on magnetic interactions in a retina fixator based on a magnetoactive elastomer seal

“…Magnetoactive elastomers (MAEs) are polymer composite materials that have magnetically sensitive filler particles embedded in the polymer matrix [1][2][3][4][5][6][7][8][9][10][11][12][13]. The main property that characterizes these smart materials is their high responsiveness to external magnetic fields.…”

“…The main property that characterizes these smart materials is their high responsiveness to external magnetic fields. Viscoelastic as well as magnetic properties of MAEs can be controlled externally [1][2][3][4][5]. The most widely used components of the composite are silicone-based soft matrices and micron-sized iron particles [3,4].…”

“…the changes to viscoelastic properties that occur in an MAE sample under the influence of external magnetic fields [1][2][3][4][5], and magnetodeformational effect, i.e. spontaneous deformation in magnetic field [6][7][8][9][10][11], serve as a basis for using MAEs as elements of tunable damping devices [12] and cell substrates [13].…”

Physicochemical Properties and Stress-Strain Compression Behaviors of a Waste based Magnetorheological Elastomers

“…The MR e ect, as stated in Eq. (2), can be recognized as the fraction of the di erence between on-state and o -state respond parameters to the o -state respond parameter [38]. In practice, the parameters can be forces [56], normal stress [75], sti ness [76], shear stress, and dissipation energy [77].…”

“…Ubaidillah et al [38] have developed a map of MREs matrix and magnetizable particles in which the commonly used matrix materials are classi ed into saturated elastomers, unsaturated elastomers, and thermoset-thermoplastic. Most of the researchers use saturated elastomers, i.e.…”
