Abstract
The electrorheological (ER) behavior of suspensions in silicone oil of phosphate cellulose particles (average particle size: 17.77 μm) was investigated at room temperature with electric fields up to 2.5 kV mm−1. For development of anhydrous ER suspensions for use at wide temperature range, it was sought the effect of the phosphate-ester reaction of celluloses on ER activity. Current density and conductivity of anhydrous ER suspensions of phosphate cellulose particles could be controlled by varying phosphoric acid concentration in phosphate-ester reactions of cellulose. When cellulose particles were treated by the phosphoric acid between 2.5M and 3.0M, ER suspensions containing phosphate cellulose particle electrorheological effect (τA/τ0) was greatest.
