Electrorheological performance of chitosan phosphate suspension

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