In the search for a new electrorheological system, silicone oil suspensions of polyaniline base, carbonized polyaniline base, and core–shell particles of carbonized polyaniline base coated with polyaniline base have been investigated. The conversion of the materials was followed by Raman spectroscopy. Although the apparent viscosity of the suspensions measured via rotational rheometer in the presence of an electric field was the same for all three samples, the core–shell structured particle-based electrorheological system showed considerably lower field-off viscosity, which resulted in higher electrorheological efficiency.
