Magnetoactive elastomers with controllable radio-absorbing properties
Materials Today Communications, 2019Abstract Magneto-active elastomers (MAEs) based on a silicon polymer matrix filled with magnetic carbonyl iron microparticles have been synthesized. Both isotropic samples and samples micro-structured by an external magnetic field have been obtained. The radio-absorbing properties of the MAEs have experimentally been studied in the frequency range 2 ...

Magnetoactive elastomer as an element of a magnetic retina fixator
Smart Materials and Structures, 2017Abstract We explore the possibility of creating an effective retinal fixator on the basis of magnetoactive elastomers (MAEs) and systems of permanent magnets. MAEs consist of silicone elastomer matrix with embedded magnetic iron microparticles.

Model of a Magnetoactive Elastomer with Structure Parameter
Proceedings of the Southwest State University. Series: Engineering and TechnologyPurpose. To propose a simple and physically reasonable way to describe basic properties of magnetoactive elastomers under the action of magnetic field and/or mechanical loading.Methods. A phenomenological approach is developed, in the framework of which the aggregation of ferroparticles in a magnetoactive elastomer is interpreted as the appearance of ...

Transient magnetorheological response of magnetoactive elastomers to step and pyramid excitations
Soft Matter, 2016Transient rheological response of magnetoactive elastomers is experimentally studied using dynamic torsion at a fixed oscillation frequency in temporally stepwise changing magnetic fields and oscillation amplitudes. For step magnetic-field excitations, at least three exponential functions are required to reasonably describe the time behavior of the ...

Magnetoactive soft elastomers-materials design, processing and applications
Reports on Progress in PhysicsAbstract Magnetoactive soft elastomers (MSEs) have garnered considerable attention in various fields of application. Their ability to reversibly change stiffness in the presence of an external magnetic field makes them applicable as dampers and shock absorbers, in soft robotics as actuators and shape-morphing structures and in the ...

Modelling Approach to Describe the Actuation Behavior of Magnetoactive Elastomers
Volume 1: Development and Characterization of Multifunctional Materials; Mechanics and Behavior of Active Materials; Modeling, Simulation and Control of Adaptive Systems, 2015Magnetoactive elastomers (MAEs) are composites made of an elastomeric matrix and a magnetizable filler material. The combination of their properties enables a MAE to undergo a change of its rheological respective damping behavior. Furthermore, it is expected that such a magnetic field can lead to an actuation of a MAE.

Development of magnetoactive elastomers for sealing eye retina detachments
Journal of Applied Polymer Science, 2018ABSTRACTMagnetoactive elastomers (MAEs) on the basis of a silicone matrix filled with carbonyl iron microparticles are developed for an envisaged application in eye surgery for treatment of complicated retinal detachments. The proposed magnetic fixator of an eye retina consists of an MAE seal placed inside an eye in the area of a retinal break, and an ...
