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 2.5 M and 3.0 M, ER suspensions containing phosphate cellulose particle electrorheological effect (tau(A)/tau(0)) was greatest.
