Abstract
Electroviscous fluids comprising particles of modified starch dispersed in high concentration in a dielectric oil, the particles containing an electrolyte which interrupts their crystallinity, renders them internally semi-conductive, and improves the surface condition of the particles in a manner to enhance their field-induced forces of attraction.
Claims5
An electroviscous fluid consisting of a dielectric oil of relatively low viscosity and particles composed essentially of starch dispersed in said oil to a volume concentration of from 40 to 60 percent, said particles including an electrolyte in amount from 1 to 10 weight percent and including water in amount from 1 to 5 weight percent.
