제목 Preparation and Properties of CP Actuator based on PPy/CB Nanocomposite Film and Solid Polymer Electrolyte
초록 Conducting polymer (CPs), such as polypyrrole (PPy), polythiophene and polyaniline, have complex dynamic structure. Their films can be easily switched by the application of small voltage and current to change volume during their electrochemical redox process. In particular, polypyrrole is most promising materials in view point of good environmental stability and ease of synthesis. In this study, the construction of CP actuator based on PPy/carbon black (CB) nanocomposite film electrodes and a solid polymer electrolyte (SPE), polyurethane/Mg(ClO4)2, was accomplished. Nanocomposite film was electrochemically polymerized from aqueous dispersions of pyrrole monomer containing carbon black. Polyurethanes as a matrix of SPE were synthesized using a two-step method based on PTMG, MDI, and 1,4-BD. SPEs with various Mg(ClO4)2 contents were prepared by solution casting. In result, we assembled PPy nanocomposite/SPE/PPy nanocomposite tri-layer actuator shown good electrochemical properties.
