Technical Field

Background
Magnetorheological fluids are liquids whose viscosity changes in response to the presence of a magnetic field. The stable suspension system is formed by uniformly dispersing soft magnetic particles with high magnetic permeability and low magnetic hysteresis in a non-magnetic carrier liquid through the action of a surfactant. Under the action of an external magnetic field, each particle is polarized into a magnetic dipole, the dipoles attract each other, and a chain-bundle-shaped structure formed between the two magnetic pole plates is transversely arranged between the pole plates like a bridge, so that the normal flow of fluid is blocked, and the solid-like characteristic is generated. When the external magnetic field is removed, the fluid returns to the original state.
The traditional magnetorheological fluid has hysteresis, and magnetic response particles with hysteresis dispersed in the magnetorheological fluid can not completely recover to a free flow state due to residual magnetism of the particles after a magnetic field is removed, so that the control process of a working device of the magnetorheological fluid is disturbed. In order to reduce the coercivity, the particles in the current magnetorheological fluids need to be on the nanometer scale, so the process control of the preparation process of the magnetorheological fluids is very important.
