Dielectric Spectroscopy of Hybrid Magnetoactive Elastomers [PDF]
Polymers, 2021 Dielectric properties of two series of magnetoactive elastomers (MAEs) based on a soft silicone matrix containing 35 vol% of magnetic particles were studied experimentally in a wide temperature range. In the first series, a hybrid filler representing a mixture of magnetically hard NdFeB particles of irregular shape and an average size of 50 μm and ...

Magnetorheological Effect of Magnetoactive Elastomer With a Permalloy Filler [PDF]
Polymers, 2020 Within the frames of this study, the synthesis of a permalloy to be used as a filler for magnetoactive and magnetorheological elastomers (MAEs and MREs) was carried out. By means of the mechanochemical method, an alloy with the composition 75 wt.% of Fe and 25 wt.% of Ni was obtained.

Microstructured Magnetoactive Elastomers for Switchable Wettability
Polymers, 2022 We demonstrate the control of wettability of non-structured and microstructured magnetoactive elastomers (MAEs) by magnetic field. The synthesized composite materials have a concentration of carbonyl iron particles of 75 wt.% (≈27 vol.%) and three different stiffnesses of the elastomer matrix.

Magnetoactive Elastomers With Periodic and Random Microstructures
International Journal of Solids and Structures, 2014 AbstractWe investigate the behavior of magnetoactive elastomers (MAEs) with periodic and random distributions of circular and elliptical fibers. For the MAEs with periodic microstructures, we develop finite element models and determine the local fields as well as the effective properties of MAEs with rectangular and quasi-hexagonal unit cells.

Magnetically Switchable Adhesion and Friction of Soft Magnetoactive Elastomers
Advanced Engineering Materials, 2022 Herein, the effect of an applied moderate (≈240 mT) magnetic field on the work of adhesion (WoA) of mechanically soft (the shear modulus ≈10 kPa) magnetoactive elastomer (MAE) samples with two different mass fractions (70 and 80 wt%) of carbonyl iron powder (CIP) is concerned.

Fullerene-Containing Modifier of Magnetoactive Elastomer
Advanced Industrial and Engineering Polymer ResearchMagnetoactive elastomer is a functional material whose properties are controlled by the parameters of the external magnetic field. A modifier that creates ordered structures with controlled nanoscale morphology is capable of intensifying the ability of a material to transfer charge.The modifier was obtained by dissociating C60 fullerene in eugenol at ...

Tunable Drop Splashing on Magnetoactive Elastomers [PDF]
Advanced Materials Interfaces, 2021 AbstractThe significant effect of an external dc magnetic field on the splashing behavior of ethanol drops impacting on the unstructured (flat) surface of soft magnetoactive elastomers (MAEs) is reported. The Weber number corresponding to the transition between the deposition and the splashing regime is reduced by ≈20% in a moderate magnetic field of ...

Analytical modeling of a magnetoactive elastomer unimorph
Smart Materials and Structures, 2023 Abstract Magnetoactive elastomers (MAEs) are capable of large deformation, shape programming, and moderately large actuation forces when driven by an external magnetic field. These capabilities enable applications such as soft grippers, biomedical devices, and actuators.

Laser Micromachining of Magnetoactive Elastomers as Enabling Technology for Magnetoresponsive Surfaces [PDF]
Advanced Materials Technologies, 2021 AbstractA simple method for structuring of the surface of a magnetoactive elastomer (MAE) on the tens of micrometers scale, which capabilities extend beyond conventional mold‐based polymer casting, is reported. The method relies on the ablation of the material by absorption of nanosecond infrared pulses from a commercial laser.
