Abstract (en)

The electroviscous fluid according to the present invention comprises a dispersion, in an electrically insulating fluid of 0.1 to 50 weight% wet-method silica whose surface adsorbed water has been replaced by a nitrile group-containing organic compound. This fluid displays a substantial increase in yield value at low voltages and excellent shear stability.
