“…The supplements that have been applied in MREs include zinc oxide and stearic acid as activators, sulfenamide (CZ) as an accelerator, sulfur as a crosslinking agent, and mercaptobenzothiazole. The types of synthetic rubber that have been applied in MREs are styrene butadiene rubber, [169] chloroprene rubber (CIIR), [117] bromobuthyl rubber (BIIR), [170] isobutylene-isoprene, [171] cis-polyisoprene, [172] cis-polybutadiene, [173][174][175][176][177][178] acrylonitrile rubber, [47,[179][180][181] and ethylenepropylene rubber. [98] Synthetic rubber-based MREs received more attention than the natural rubber MREs since they have higher resistance to oil, better aging, and weathering as well as resilience over a wide temperature range.…”

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.

“…13 Recently, we also observed that the influence of magnetic field on the loss factor is small. 24 Therefore, the development of other methods to control the damping properties of the MREs is highly desirable. It is noted that the loss factor change of the MR gels 25 is bigger than that of the MREs 2,13,24 with increasing magnetic field.…”

A novel kind of magnetorheological elastomers (MREs) with controllable damping properties was developed in this study. Polycaprolactone (PCL) was selected as the temperature-controllable component in the cis-polybutadiene rubber (BR) based MREs. Several samples with different BR/PCL mass ratio matrixes were prepared. The dynamic performances of the samples, including loss factor, shear storage modulus, and loss modulus, were measured with a rheometer. Differential scanning calorimetry (DSC) analysis indicated that PCL is a phase change material and it can transform from a semicrystalline solid to a liquated soft material by increasing the surrounding temperature above the PCL melting point. Experimental results showed that the damping properties of the MREs can be controlled by varying the PCL weight ratio, the temperature, and the magnetic field. The controlling mechanism was proposed and the influence factors were analyzed. Last, it was also observed that the magnetoinduced modulus and the MR effect of the MREs were changed remarkably by the added PCL under different temperatures.

“…Gong et al [13] and Lokander and Stenberg [9] reported the advantageously influence on the MR effect of the addition of plasticizers to the silicon rubber due to the decrease of the polymer matrix stiffness. Jiang et al [14] indicate on the positive effect of the particles surface modification on the increase of the MR effect, while Zhang et al [15], Fan et al [16] and Li et al [17] show that the enhancement of the particle-polymer matrix interaction leads to the decrease of MR effect due to the existence of bound-rubber phenomenon. The improvement of filler-matrix interaction is an effective way to improve the mechanical properties of materials; however in the case of MREs it can affect the MR effect.…”

The reported studies are related to a new group of intelligent materials, such as magnetorheological elastomers (MREs), which are composites of ferromagnetic particles embedded in elastomer matrix. Studies on fabrication of MREs were carried out using two different polyurethane elastomers as a matrix, ferromagnetic particles and coupling agent. The matrices were differed in elastomer stiffness and hardness. As a ferromagnetic component carbonyl-iron powder with particle size of 6-9 µm was used. Particles were oriented into chains under the external magnetic field of 240 kA/m. Samples with anisotropic particles arrangement and particles volume fraction equal to 11.5% were examined. Microstructure of MREs was observed using Scanning Electron Microscopy. Structural and magnetic anisotropy of the MREs was derived from the magnetic studies. Rheological properties of the MREs, such as storage and loss modulus and loss factor, were characterized as a function of shear frequency and strength of the magnetic field. Absolute and relative magnetorheological effects were calculated taking the microstructure into account, which was formed in the course of the MRE fabrication, by changing the elastomer type and application of the coupling agent. As a result of the studies it was found that the MREs with stiffer matrix exhibit much lower MR effect than the soft ones. Also the application of coupling agent lead to a decrease of MR effect by the formation of bound elastomer surrounding the particles, which increases the stiffness of the matrix.
