Abstract
Dedoped polyaniline (PAn) particles with special core-shell structure were synthesized by chemical oxidation polymerization of aniline (An) through dropping An into oxidant solution with different charging sequ ences, and partially dedoped with concentrated ammonia water, then mix ed with chlorinated paraffin oil to form anhydrous electrorheological. fluid (ERF). The ERF has a large static yield stress of 16.3 kPa and concomitant low current density of 2.67 mu A/cm(2) under direct curren t electric field strength of 2.8 kV/mm.
