- This paper focuses on the influence of metal ions on electrorheological and electric properties. The metal
particle has not been used as an electrorheological suspension due to the high conductivity and the
sedimentation in the suspension although it is expected good electrical properties. In this study, carboxyl
group and metal ions were introduced to the surface of the chitosan particle to confirm the influence of
the metal ion on the electrorheological property. Although the synthesized chitosan succinate showed
good electrorheological property, its metal complex (chitosan succinate–metal complex formed with
Al3+, Cu2+, Ni2+, Fe2+, or Zn2+) dispersed suspension showed the low electro-response property and high
values of current density and conductivity.
