Chitosan and chitosan phosphate suspensions showed a typical ER response (Bingham now behavior) upon application of an electric field. However, chitosan phosphate suspension exhibited excellent shear yield stress compared with chitosan suspension. The difference in behavior results from the difference in the conductivity of the chitosan and chitosan phosphate particles due to their degree of the polarizability. The shear stress for chitosan and chitosan phosphate suspensions showed a linear dependence on the volume fraction of particles. The values of structure factor, A(s) obtained 1 and 3 similar to4 for chitosan and chitosan phosphate suspensions and it may be due to the formation of single-row chains and multiple chains upon application of the electric field Throughtout the experimental results, chitosan and chitosan phosphate suspensions were shown to be an ER fluid.
