ELECTRICAL-CONDUCTIVITY OF FLOWING POLYANILINE SUSPENSIONS

The electrical conductivity of suspensions composed of electrically co nducting polyaniline in nonconducting liquid (2,2,4-trichlorobenzene) was measured as a function of electric-field strength in dependence on the shear rate in Couette flow. The electrical properties are discuss ed in terms of the organization of conducting particles in electric fi elds and related to the Mason number, which is used to describe the el ectrorheological behavior of suspensions in the literature.
