“…Rheological measurements were performed using an Anton Paar (MCR 301) rheometer with a MR cell using parallel plate geometry with a plate diameter of 20 mm (MRD 180). This system is often used for MR measurements . The samples had a diameter of 20 mm, either dictated by the mold size or obtained by die cutting.…”

Highly compliant elastomers with a shear storage modulus as low as 25 Pa are prepared using commercially available silicone, plasticizer, and tactile mutator silicone additive. They are used as matrix material for magneto‐active elastomers (MAEs) with carbonyl iron contents between 0 and 85 wt %. In the absence of an external magnetic field, the storage modulus of MAEs based on two selected mixtures ranges between ∼100 Pa and ∼2000 Pa. Addition of a mutator to the matrix mixture results in a long post‐cure period depending on the curing temperature and the initial mixture. In the presence of a magnetic field, the presented MAEs exhibit a strong magneto‐induced change in storage modulus resulting in a colossal magnetorheological effect of >106 % which is ∼30 times higher than previously reported values. The results are of interest in applications using such elastomers as cell substrates with magnetically tunable rigidity. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 39793.

Aiming to improve the shear yield stress of magnetorheological fluid, magnetorheological fluids with different particle characteristics are prepared, and the influence rules of particle mass fraction, particle size, nanoparticles content and application temperature on shear yield stress are investigated. Experimental results indicate that shear yield stress increases approximate linearly with the enhancement of particle mass fraction. Particle size and the nanoparticles within 10% mass fraction can improve the shear yield stress effectively. When the application temperature is higher than 100 o C, the shear yield stress decreases rapidly because of thermal expansion and thermal magnetization effect.

“…Clearly, this special kind of thermal sensitive characteristic not only reduces the sentimental defects of the traditional MRFs but also supplies a feasible way for multifunctional MR materials. Actually, the previously reported grease-based MR materials also exhibits such a thermal responsive MR behavior [73,74]. Although the physical state of the MR grease has not been demonstrated in the manuscript, it was estimated to be a kind of MRP with a small starting storage modulus, because the authors have claimed that this product had a strong solid-like structure rather than a fluid-like structure under external magnetic field.…”

Different from the traditional magnetorheological (MR) fluids and elastomers, the magnetic particles in the plastic MR materials are not 'deadly' trapped in the polymer matrix; thus, the MR plastomers exhibit higher MR effects and lower sedimentation. The plastic MR materials have attracted increasing attention, and the relevant fundamental mechanisms and practical applications have been intensively studied due to their unique physical and mechanical properties. In this highlight, we have mainly reviewed the preparation and the rheological properties of the MR plastomers. The formation mechanism of the MR plastomers has also been briefly summarized.
