Flow Control by an Artificial Muscle Based on a Conducting Polymer

We have proposed the flow control by using an artificial muscle based on the conducting polymer. In order to utilize the artificial muscle for flow control, it is important to clarify the mechanical properties on the artificial muscle based on the conducting polymer. The purpose of this study is to clarify the mechanical properties on artificial muscle and possibility of flow control by using it. We have measured the tensile force generated by artificial muscle in the distilled water. Moreover, we have observed the actuation of artificial muscle based on the conducting polymer in water tunnel. The tensile force of artificial muscle increased as the electrode potential increased. The averaged maximum tensile force did not depend on the scan rate of electrode potential. It depended on the electrode potential and was almost constant. However, the time for reaching maximum tensile force depended on the scan rate. The artificial muscle performed the bending actuation sufficiently not only static water but also running water. Therefore, it can be considered that the artificial muscle will be applied to the actuator for flow control.

And Training

Work behaviours and training effects of artificial muscle based on electrochemomechanical strain (ECMS) of conducting polymer, polypyrrole (PPy) films have been studied under tensile stress up to 5 MPa. PPy films were electrochemically deposited in dodecylbenzene sulfonic acid. Cyclic voltammetry and ECMS were measured in 1M NaCl aqueous solutions. At higher stress, a larger creeping due to the conformation change, slipping and/or breaking of polymer chains was observed. After the experience of large tensile stress an appreciable increase of strain (training effect) was observed, when the film was actuated at lower tensile stress. The training effect was discussed in terms of the relaxation of anisotropic strain induced during the creeping. The conversion efficiency from electrical to mechanical energies was 0.07 % at 3 - 4 MPa being the maximum. Degradation of film was found to be accelerated under higher tensile stress from the measurement of conductivity.
