Abstract:
To investigate the effect of dopant size, especially that of anion size, on the actuation behaviour of polypyrrole (PPy) actuator, the authors prepared PPy actuators with three types of dopants: sodium perchlorate (NaClO4 with small anion), para-toluene sulfonate (pTS with medium anion) and dodecyl benzene sulfonate (DBS with bulky anion). The largest displacements of 12·95, 8·36 and 9·62 mm were obtained in PPy actuators with NaClO4, pTS and DBS respectively. This result was caused by the cation and anion size of dopant used in this study.Keywords: CONDUCTING POLYMER ACTUATOR; DOPANT SIZE; SOLID POLYMER ELECTROLYTE; ACTUATION MECHANISM
