Abstract
Novel bending actuators were made solely from electrochemically polymerized conducting polymer materials. The working principle for these free-standing conducting polymer (CP) films is based on different anion- and cation-dominated actuation for the two layers. Synthesis conditions for the two layers of the same polymer film have been chosen such that the mobility of cations and anions in the considered potential window is different. Polymerization of CP layers of this nature on top of each other results in a sandwich structure with bilayer functionality in a properly chosen electrolyte. The results of a comparative study of various combinations of sandwiched PEDOT films in terms of actuation properties are presented in this study. Free-standing films of PEDOT linear actuators electrodeposited in the same electrolyte at different polymerization potentials were investigated by means of electro-chemo-mechanical deformation measurements. PEDOT-PEDOT bilayer functionality is studied in this work with a view to their bending actuation properties.
