Magnet filler-polymer matrix composites (Magpol) are an emerging class of morphing materials. Applications of Magpol can include artificial muscles, drug delivery, adaptive optics and self healing structures. Advantages of Magpol include remote contactless actuation, several actuation modes, high actuation strain and strain rate, self-sensing and quick response. The actuation modes of Magpol, its dynamic properties, work output and transduction characteristics are described. Analogies between Magpol actuation and phase transformations are presented. As an illustration of Magpol actuation, a proof of concept artificial muscle is presented. Current applications and future prospects are described.

“…The magnetic fi eld can infl uence on the chemical reaction containing radicals and can induce orientation of most organic polymer molecules [5][6][7][8] . Although some literatures concerning the effect of magnetic field on the electro chemical polymerization of aniline and secondary doping of PAn have been published, none of them focus on the chemical oxidative polymerization of aniline in magnetic fi eld [9][10][11][12][13] .…”

Polyaniline was obtained by chemical oxidation in the microemulsion system consisting of aniline, emulsifi er, assistant emulsifi er and water in magnetic fi eld (0 T, 0.2 T, 0.4 T, 0.6 T). The effect of magnetic fi eld on the polymerization rate and the inherent viscosity of polyaniline were studied. The molecular structure of polyaniline was characterized by IR spectra and the thermal degradation behavior was assessed using TG techniques. The results show that the polymerization rate, molecular weight, thermal stability and conductivity of the synthesized polyaniline enhanced and no effect on the basic structural units of polyaniline was observed in magnetic fi eld. Within the range of the intensity of magnetic fi eld studied, the magnetic fi eld of 0.4 T exerts the largest infl uence on polymerization of aniline.

“…Coupling the elastic medium with the magnetic properties of the magnetic particles gives opportunity to control the elastic behavior of the ferrogel by means of an external magnetic field. [2,3] In most experiments concerning ferrogels, magnetic particles with a typical diameter of the order of %10 nm are the elementary carriers of the magnetic moment. These particles are embedded in a flexible polymer network and eventually attached to the chains.…”

“…[2,3] In non-homogeneous magnetic fields an abrupt volume transition was observed. The gradient of the magnetic field generates the force that drives the magnetic particles in the gradient direction, thus deforming the ferrogel.…”

“…[2] It was shown that a homogeneous magnetic field leads to an increase of Young's module by several orders. [3] Naturally, a theory for such systems is very difficult and suffers from many different length scales. The development of a detailed theory that takes into account all the aspects described by the above mentioned experiments seems to be too difficult.…”

Summary: This paper introduces a simple mean‐field theory for gels with magnetic properties. The main emphasis in this paper is the discussion of the scattering properties. Therefore, a simple model is introduced, such that the chains carry magnetic moments along their main axis. Naturally these magnetic moments interact sensitively to theory orientation with each other. Thus a distinguished interplay between chain and dipole orientation induces strong coupling between the macroscopic deformation and magnetic properties. These effects can be experimentally demonstrated with scattering methods. Here some mean‐field expressions for the structure factors are predicted and discussed in some detail.
