| Abstract(in English) | A method of preparing a large-size anisotropic polypyrrole (PPy) film using a slab vessel consisting of poly(tetrafluoroethylene) (PTFE) walls as well as its actuation properties is reported. The PPy film can be grown along one side of the PTFE walls and exhibits a morphological anisotropy along the thickness direction. A piece of it bends and reverts in a regular direction during a redox cycle without the use of any addditional processes such as lamination. The actuation characteristics of the anisotropic PPy film strongly depend on the size of the cation in the driving electrolyte. The bending of this actuator at room temperature becomes slower for larger cations. The temperature dependence of the characteristics of the anisotropic PPy film as actuator has been investigated. As the temperature increases, the arrival time of the actuator becomes shorter in all electrolyte solutions. This can be understood in terms of the thermally activated microscopic movement of polymer chains. It is also found that this actuator can lift an object which weighs more than 25 times of the weight of the actuator itself. |
