ABSTRACT:
An electrorheological fluid comprising an electrically insulating liquid and acid, iodine or alcohol-treated, or iodine-treated and subsequently electrically insulating film-coated, dispersible carbonaceous particles dispersed therein has a high electrorheological effect even without lowering in a high temperature region, though it is a water-free system.
