Electrorheological behavior of heat-treated sepiolite suspension
In this study, we investigated the electrorheological characteristics of a fibrous hydrated magnesium silicate, sepiolite suspension. The sepiolite nanoparticles were heat-treated between 150 and 900 °C, and 2 wt% sepiolite was dispersed in silicone oil. The structural change of the baked particles was analyzed. The effects of the particle loading and applied voltage were evaluated. It was found that the heat-treated sepiolite suspension showed relatively higher viscosity, storage modulus and loss modulus. In addition, as the applied voltage increased, the shear yield stress increased. When a 9 kV/mm direct current (DC) field was applied, a shear yield stress of 16.8 kPa was measured.
