Magnetoactive Elastomers: Characterization, Modeling and Applications

Dear Colleagues,

Magnetoactive elastomers (MAEs) are multifunctional smart composite materials consisting of elastomeric medium impregnated with micron-sized soft or hard magnetic particles. Under the application of an external magnetic field, MAEs can vary their mechanical properties (stiffness and damping) semi-actively. Moreover, they can provide controlled actuation owing to their inherent magnetostriction effect. These properties combined with their unique features such as flexibility, fast response and low-power requirement have made MAEs unique smart materials for the development of adaptive systems for a wide range of applications ranging from transportation systems to medical devices. While significant research has been conducted to understand the response behavior of MAEs under mechanical and magnetic loading, there are still significant research gaps in the thorough characterization of MAEs under shear, tension/compression and combined shear and Tension/compression loading; development of physic-based, phenomenological and AI models to predict the nonlinear hysteresis behavior and actuation of MAEs under varied mechanical and magnetic loading conditions; development of novel MAE materials with improved MR effect and 4D printing technology of MAEs. This Special Issue is aimed at providing selected contributions on advances in the characterization, modeling and application of magnetoactive materials Potential topics include, but are not limited to, characterization of magnetoactive elastomers with soft magnetic particles (S-MAEs) characterization of magnetoactive elastomers with hard magnetic particles (H-MAEs) isotropic and anisotropic MAEs magnetostriction in MAEs effect of material factors (ex. type of polymeric materials, size and shape of iron particles, iron volume fraction) and temperature models to predict the mechanical and actuation properties of MAEs 4D printing of MAEs potential applications of S-MAEs and H-MAEs.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
