A physical model of conducting islands is proposed to explaine the characterizations of dielectric loss of conducting polymers caused by interface polarizability. According to this model, the behavior of the electric loss of conducting polymers caused by conducting islands depends on the dielectric constant and the conductivity of conducting islands itself, as well as its volume fraction occupied in the conducting polymers. The characterizations of dielectric loss of conducting polymers proposed by the model of conducting island are consistent with the observations obtained from experiments of microwave absorption of conducting polymers.
