Effect of the concentration of four types of carbon black, namely, HAF, FEF, ISAF and GPF, on the electrical conductivity of SBR (1502) was studied. The anomalous behavior of conductivity [σmin in σ(T) curves] becomes more pronounced as we approach a characteristic value of carbon concentration, F0, at which maximum anomaly occurs; F0 was found to depend on the type of carbon black. Moreover, the depth of the valley shape of the σ(T) curve increases with the particle size of carbon black used.read more
