摘要：

The electrorheological (ER) performance of chitosan phosphate suspension in silicone oil was investigated. Chitosan phosphate suspension showed a typical ER response (Bingham flow behavior) and exhibited an excellent shear yield stress due to the formation of multiple chains upon the application of the electric field. The shear stress for chitosan phosphate suspension showed a linear dependence on the volume fraction of particles and 1.67 power of the electric field. The experimental results for the chitosan phosphate suspension correlated with the conduction model for ER response.
