摘要：

Polypyrrole film with porous and compact zones in its vertical direction has been synthesized by direct oxidation of pyrrole in the mixed solvent of acetonitrile and dichloromethane contained a certain amount of anion surfactant of sodium 1,4-bis(2-ethylhexyl)sulfosuccinate (AOT). The actuator based on this single-layer film bends uniformly with the maximum bending angle much larger than 90 and has a fast response rate (similar to 60 s(-1) at 1.0 V versus SCE) and a long lifetime (> 20,000 cycles). The high performance of this actuator is mainly due to that the PPy film has a high conductivity and the actuator does not have delamination problem. (c) 2005 Elsevier B.V. All rights reserved.
