Polyaniline (PANI) particles were synthesized by the chemical oxidation of aniline in acidic media, then the optimum conductivities in a semiconductive range for electrorheological (ER) application were achieved by adjusting the pH of an aqueous solution containing PANI particles. A semi-active ER damper filled with the PANI-based ER fluid was then investigated under different electric field strengths. The damping forces measured could be controlled by tuning the applied electric field for different piston velocities.
