Magnetic Rubber Having Magnetic Clusters Composed of Metal Particles

Abstract

For the purpose of assembling metal particles on a nano- or microscale, in a previous investigation the authors had succeeded in extracting magnetic clusters from an intelligent fluid responsive to a magnetic field. The clusters are shaped like rods or needles and range from macroscopic to microscopic in size. In the present paper, a method for producing silicon rubber that contains the magnetic clusters is presented and its magnetic, mechanical, and physical properties are discussed. This new material shows superpara and anisotropic magnetization. In addition, the tensile strain of the material in relation to normal stress changes due to the existence of the magnetic clusters is studied. This material can be used in engineering applications.
