<p>Electroviscous (EV) fluids consisting of solid hydrophilic particles dispersed in hydrophobic liquids, where the liquid contains a diaryl derivative component of general formula I$(10,)$in which R is CY2, O, S, SO, SO2, SiF2, or O-SiY2-O, X?1 and X2¿ are halogens, (m + n) is between 1 and 3 on average, and (p + q) is between 0 and 1 on average. EV fluids containing these novel components possess generally improved properties in terms of lower viscosities, electrical conductivities, toxicities and freezing points. In a preferred embodiment, the component is a mixture of brominated diphenyl methanes in which R is CH¿2? n = 0, X?1¿ = Br, (m + n) is approximately one, and (p + q) = 0.</p> |
