摘要：
The electrorheological (ER) behavior of a chitosan succinate suspension was investigated by varying the electric fields, volume fractions of particles, and shear rates, respectively. The chitosan succinate suspension showed a typical ER response caused by the polarizability of an amide polar group and shear yield stress due to the formation of multiple chains upon application of an electric field. The shear stress for the suspension exhibited a linear dependence on the volume fraction of particles and an electric field power of 1.88. On the basis of the results, the suspension formulated chitosan succinate as the disperse phase was found to be an anhydrous ER fluid. (C) 2002 Elsevier Science B.V. All rights reserved.
