| 제목 | Tri-layered CP Actuator based on Polypyrrole and Solid Polymer Electrolyte Working in Air |
| 초록 | The conducting polymer, polypyrrole(PPy), undergoes a volume change when its oxidation state is changed electrochemically by the application of low voltage. This volume change is due to ion movements in and out of the polymer film. However, it may be an impediment to the practical use of PPy actuator that usually requires electrolyte solution for actuation. Our research theme is focussed on this problem. In this work, the construction of a new solid state CP actuator, fully polymeric, based on two PPy film electrodes and a solid polymer electrolyte(SPE), polyurethane/Mg(ClO4)2 was accomplished. PPy was grown electrochemically on stainless steel electrode with sodium perchlorate(NaClO4) as a dopant. PPy was characterized by using 4-point probe technique, scanning electron microscopy(SEM) and infrared spectroscopy. Polyurethanes(PUs) were synthesized using a two-step method based on polydimethylsiloxane(PDMS) with different molecular weights 1001, 1809, and 3205. The properties of SPE were measured by using fourier transform-infrared spectroscopy(FT-IR), alternative current(AC) impedance measurements, and differential scanning calorimetry(DSC). We fabricated the tri-layered CP actuator composed with one SPE layer between two PPy layers and measured the displacement. All the results obtained in this work show the feasibility of electrochemomechanical devices based on PPy and SPE film able to work in air. |
