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 (NaClO<subscript>4</subscript> 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 NaClO<subscript>4</subscript>, pTS and DBS respectively. This result was caused by the cation and anion size of dopant used in this study. [ABSTRACT FROM AUTHOR]
