“…Researches have been conducted to enhance the mechanical and MR characteristics of MREs by adding non-magnetic fillers as additives to MREs. Different types of non-magnetic fillers include reinforcing agents [ 92 , 93 , 94 , 95 ], plasticizers [ 96 , 97 , 98 ], and crosslink agents [ 99 , 100 ] that are related to the mechanical characteristics of MREs, in addition to the important magnetic fillers to increase MR properties. Mechanical reinforcing agents include carbon nanotube (CNT) [ 92 ], graphene [ 93 ], graphite [ 94 ], and carbon black [ 95 ].…”

Magnetorheological (MR) elastomers become one of the most powerful smart and advanced materials that can be tuned reversibly, finely, and quickly in terms of their mechanical and viscoelastic properties by an input magnetic field. They are composite materials in which magnetizable particles are dispersed in solid base elastomers. Their distinctive behaviors are relying on the type and size of dispersed magnetic particles, the type of elastomer matrix, and the type of non-magnetic fillers such as plasticizer, carbon black, and crosslink agent. With these controllable characteristics, they can be applied to various applications such as vibration absorber, isolator, magnetoresistor, and electromagnetic wave absorption. This review provides a summary of the fabrication, properties, and applications of MR elastomers made of various elastomeric materials.

“…Addition of small amounts of additives, in the 0.1–15 wt% range, to MR solids causes an improvement in the properties of the materials. The additives can contribute to enhancing the MR effect of MR solids, depending on their quality and quantity . Moreover, additives improve the processing ability and reduce the cost of the materials .…”

“…Lokander and Stenberg introduced phthalate ester‐based plasticizers in 2003 . Later, these plasticizers became the focus of many studies on the preparation of MR elastomers . In the earliest study on phthalate ester‐based plasticizers, diethylhexyl phthalate (DEHP) was used as a plasticizer for nitrile rubber‐based isotropic MR elastomers; the addition of DEHP led to an enhancement in the shear storage modulus of the MR elastomers .…”

“…For instance, the MR elastomer with 15 wt% DIOP, exhibited an MR effect of 387%, and storage modulus in the range 0.3–1.46 MPa at 1000 mT, which was 58 times greater than that of MR elastomers without additives. Kimura et al utilized four different types of phthalate ester‐based plasticizers in a study conducted in 2014 . They used dioctyl phthalate (DOP), dimethyl phthalate (DMP), butyl benzyl phthalate (BBP), and bis (2‐methyloctyl) phthalate (DINP) as plasticizers for PU‐based MR elastomers, as shown in Figure (a).…”

Role of Additives in Enhancing the Rheological Properties of Magnetorheological Solids: A Review

et al. 2018

View full text Add to dashboard Cite

During the last two decades, magnetorheological (MR) materials have attracted a significant amount of attention because of their tremendous potential for engineering applications. This review focuses on the role of various additives in enhancing the magnetic field-dependent rheological characteristics of solid and thixotropic matrice-based MR materials (hereafter referred to as MR solids). Typically, MR solids consist of solid or semi-solid matrices filled with magnetizable particles. However, additives need to be used to improve their performance such as the MR effect. This parameter is typically determined by the field-dependent dynamic modulus. Three different groups of additives would be introduced in the review namely plasticizers, carbon-and chromiumbased additives. Compared to particles in the common matrix without a softener, those in matrices with additives which act as matrix softeners will be aligned easier during curing. In fact, the interfaces bonding between matrixparticles would be improved that subsequently enhanced the magnetically induced viscoelastic properties of MRE. In this review, the influences of several additives on the MR effect of various MR solids including MR elastomers, MR greases, and MR gels, which are recognized as efficient smart materials for practical applications in various engineering fields, are surveyed and discussed.

The magnetorheological elastomers (MREs) are novel multifunctional materials wherein their viscoelastic properties can be varied instantly under an application of applied magnetic field. Due to their field‐dependent stiffness and damping properties, MREs are widely used in the development and design of MRE‐based adaptive vibration isolators and absorbers and also biomedical engineering. Moreover, MREs due to their inherent magnetostriction effect have enormous potential for the development of soft actuators. The dynamic behavior of MREs is affected by various material parameters (e.g., matrix and particle types, particle concentration, additives) as well as mechanical and magnetic loading parameters (e.g., frequency, amplitude, temperature, magnetic flux density). Understanding and predicting the effect of materials and loading parameters on the response behavior of MREs are of paramount importance for the design of MRE‐based adaptive structures and systems. This review paper mainly aims to provide a comprehensive study of material constitutive models to predict the nonlinear magnetomechanical behavior of MREs. Particular emphasis is paid to physics‐based models including continuum‐ and microstructure‐based models. Moreover, phenomenological models describing the dynamic magnetoviscoelastic behavior of MREs as well as the effect of temperature on the magnetomechanical behavior of such materials are properly addressed.
