高活性聚苯胺电流变液的制备与性能研究官建国，谢洪泉，过俊石（华中理工大学化学系，武汉，４３００７４）关键词电流变液，聚苯胺，反掺杂，电荷迁移极化电流变液（ＥＲＦ）是重要的人工智能材料和高效机电一体化的功能液体［１］．目前，研究ＥＲＦ技术的关键是提高Ｅ...

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 sequences,and partially dedoped with concentrated ammonia water,then mixed 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 μA/cm￣2 under direct current electric field strength of 2.8 kV/mm.
