Nanomechanics of Electrorheological Suspensions with Polymer Dispersed Phase. Quantum-Mechanical Simulation

Abstract

The microscopic structure and mechanical properties of electrorheological fluids in an electric field were investigated by means of quantum-mechanical computer simulation. Modified polyimides were considered as the solid-phase particles. The simulation was performed for electric fields of different intensity. The microscopic characteristics of shear deformation (shear modulus) of the electrorheological fluids were considered by varying the chemical structure of the dispersed phase, dielectric permittivity of a viscous medium, magnitude of the shear strain, and concentration of dielectric particles of the solid phase.
