Annealing effect on electromechanical behaviour of polyanilines organic acids-doped

It was observed that both the polyanilines exhibit a strong change of their resistance value as function of the compression load acting on the samples. Moreover, PANI2 shows a high resistance which is a good property for insert the element into any measurement circuit avoiding problems of impedance losses due to cables or other circuit elements. The results will also show that both PANIs have steady behaviour at high temperatures up to 85°-100 °C.
