Polyaniline suspensions in 1,2,4-trichlorobenzene produced solid composites after freezing. Changes in electric conductivity after the solidification and during the melting transition have been investigated in dependence on conducting polymer concentration. Below the percolation threshold, the...

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...

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....

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...
