The flow behaviour of silicone-oil suspensions of five types of silica particles coated with a polyaniline base in a DC electric field has been linked to their dielectric properties. The relaxation frequencies corresponding to the position of the dielectric-loss maxima in the frequency spectra...

Investigation of the electrorheological (ER) effect of silicone–oil suspensions of silica particles coated with polyaniline (PANI) base in a DC electric field revealed that breaking stress, as a criterion of the intensity of the ER phenomenon, steeply increased at first with coating thickness....
