Electrorheology, temperature effect

J.B. Yin, X. Xia, L.Q. Xiang, X.P. Zhao, Temperature effect of electrorheological fluids based on polyaniline derived carbonaceous nanotubes. Smart Mater. Struct., 2011, 20, 015002. 

The effect of temperature on the electrorheology was examined by Shul man and Matsepuro (618). Additional patented compositions have been described (619, 620). 

Rheobay Electrorheological Fluid. (Provisional product information TP AI 3566. Miles Industrial Chemical Division, USA.) Although the effect of a change of temperature will be evidenced in the above properties (and may affect the settlement rate of the solid, which can only be matched perfectly with the base fluid at one temperature), none is more significant than its effect on current density J. Here, a small increase in temperature can raise the current consmnption considerably, and vice versa. This is a major problem area of ERF. Certainly this factor alone is sufficient justification for the use of a simple approach to the initial characterisation, fluid comparability problem and design procedures. Different temperatures can change slopes of the r, 7-characteristic increased temperature can often increase current to that for the optimmn (however small it is) and Te performance and/or give a level Te f j) characteristic or thereabouts.
