ABSTRACT:
Electrorheological fluids display swift and reversible increase in apparent viscosity under application of an electrical potential difference to the fluid, and are composed generally of electrical insulating oily medium and dielectric fine-particles dispersed therein.
It is an object of the present invention to provide an electrorheological fluid capable of exhibiting enhanced electrorheological effect with smaller electric power consumption.
Electrorheological fluid according to the present invention comprises particulates having a specific gravity of not smaller than 1.2 and water content of not larger than 4 wt. % dispersed in an electrical insulating oily medium havingf P.dbd.N bonds in the molecule.
