Description
Summary:Ionic polymer-polymer composites (IP 2 C) have been developed and studied as energy harvesters. IP 2 C consists of a porous ion-exchange polymer, the surface of which is coated on both sides with conductive polymer electrodes. PEDOT:PSS and PANI obtained by drop-casting method and oxidative polymerization of aniline respectively were used as electrodes. It has been found that IP 2 C harvesters are characterized by linear dependence of output signal amplitude from displacement amplitude in the range of 0.1...2 cm. The mechanoelectrical conversion coefficient for structures with PEDOT:PSS and PANI electrodes was 3.3 mV/cm 2 and 4 mV/cm 2 respectively. The IP 2 C structures with the PANI electrodes are capable of generating a signal with a higher amplitude than in the case of PEDOT:PSS electrodes, which is explained by the difference in the manufacturing techniques. A battery charging circuit using an IP 2 C harvester has been developed and methods for increasing the output signal have been proposed.
