The study on conductivity and electrorheology of polyacene quinone radical polymer dispersion

Through the research of the conductivity and electrorheological (ER) properties of semiconducting polyacene quinone radical (PAQR) polymer dispersion in silicon oil, it is found that the current-voltage curve and torque (shear stress) voltage curve both confirm the power law under scale assumption. The power index depends little on temperature and it increases greatly as the shear rate decreases with large and similar value. It is no doubt that the correlation is very important to deepen the understanding of ER properties and the role of conductivity of this kind of materials
