Electrorheological and dielectric properties of suspensions of polyphenylenediamine isomers in silicone oil have been investigated. The effectiveness of the base forms of polymers was higher than that of their protonated counterparts. The dielectric spectra showed a low rate of polarization...

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...
