“…They have received wide attention owing to their unique properties, including viscosity, storage and loss moduli, and elasticity [3,4]. Polarizable particles in an ER fluid form chains along the direction of the E field, significantly increasing the viscosity, and the fluid changes from liquid to a solid-like state rapidly, and vice versa [5,6]. The medium returns to its normal liquid form when the E field is removed, rendering ER fluids valuable for various applications, including clutch systems, haptic devices, and dampers [7][8][9].…”

“…The medium returns to its normal liquid form when the E field is removed, rendering ER fluids valuable for various applications, including clutch systems, haptic devices, and dampers [7][8][9]. Drastic changes in the properties of ER fluids, such as the shear stress and viscosity, can be used to evaluate the ER performance of the fluids under different E field strengths [5,10]. The shear stress reflects the resistance of a fluid to flow or deformation, whereas the viscosity indicates its thickness or resistance to shear stress.…”

The use of plate-like materials to induce a percolation gel-like effect in electrorheological (ER) fluids is sparsely documented. Hence, we dispersed plate-like materials, namely natural mica, synthetic mica, and glass, as well as their pulverized particles, in various concentrations in silicone oil to form ER fluids. Subsequently, the rheological properties of the fluids were evaluated and compared to identify the threshold concentration for percolating a gel-like state. The shear stress and viscoelastic moduli under zero-field conditions confirmed that plate-like materials can be used to induce percolation gel-like effects in ER fluids. This is because of the high aspect ratio of the materials, which enhances their physical stability. In practical ER investigations, ER fluids based on synthetic mica (30.0 wt%) showed the highest yield stress of 516.2 Pa under an electric field strength of 3.0 kV mm−1. This was attributed to the formation of large-cluster networks and additional polarization induced by the ions. This study provides a practical approach for developing a new type of gel-like ER fluid.
