Recently, Song and Lin  reported electrorheological (ER) fluids based on the synthesized bithiazole ring and p-aminobenzoic acid containing new polymer system, and CeCl4 mixed polymer-Ce4+ complex. Two different ER fluids systems were prepared and their electrical properties were compared each other. It was observed that the cerium ion (Ce4+) enhanced ER activity, in which the yield stresses increased compared with pure polymer based ER fluid under an applied electric field.
The typical ER fluid implies a suspension of semiconducting or dielectric solid particles in non-conducting liquid media [2, 3, 4, 5, 6, 7], exhibiting reversible and drastic changes in their rheological properties which include a large increase in apparent viscosity and the formation of reversible suspension microstructures under an applied electric field [8, 9] along with its magnetically analogous magnetorheological suspensions under an external magnetic field [10, 11, 12]. The reversible behavior on the...
