Microscopic Simulation of Magnetorheological Properties in Magnetic Elastomers
This paper proposes a theoretical model for the magnetorheological properties of magnetic elastomers composed of micron-sized particles, which are magnetizable, have no intrinsic magnetic moment, and occur in a soft polymer medium. The study examines two types of composites: initially isotropic ones (synthesized in the absence of magnetic field) and anisotropic ones (polymerized in a magnetic field promoting aggregation of the particles into anisotropic structures). The data obtained show that the formation of anisotropic structures at the stage of the synthesis leads to a substantial increase in the macroscopic shear rigidity of the composite. The theoretical results are in quantitative agreement with experimental data.
期刊介绍:
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
