Magnetic field intensity effect on plane capacitors based on hybrid magnetorheological elastomers with graphene nanoparticles

Abstract

Abstract Hybrid magnetorheological elastomers (hMREs) are prepared using silicone rubber (SR), silicone oil (SO), carbonyl iron (CI), graphene nanoparticles (nGr) and cotton fabric. For volume concentration of SO and CI fixed at 20%, and various volume concentrations of SR and nGr we obtain four plane electric capacitors (FCs). We measure the electrical capacitance C of FCs as a function of the intensity of a magnetic field H. Using elements of elasticity theory we determine the components of elasticity ϵxx and of mechanical tensions τxx, as well as the modulus of elasticity E. We present and discuss the obtained results.
