| 제목 | The characterization of IPMCs in accordance with the cycle number of plating platinum electrode |
| 초록 | Ionic Polymer Metal Composite(IPMC) is a kind of EAP that bends in response to the electrical activation as a result of the movement of mobile cations in the polymer network. IPMCs are composed of electrolyte and metal electrodes. Noble metals, such as gold and platinum, are used as metal electrodes. And the surface resistance is influenced by the state of metal electrodes. The surface resistance affect the actuation performance of the IPMCs. Ion-exchange membranes, such as Nafion and Flemion, are used as the electrolyte. In this study, poly(vinylidene fluoride-co-hexafluoro propylen) (PVDF-co-HFP) and poly(ethylene-alt-tetrafluoroethylene) (ETFE) were grafted with styrene using γ-ray irradation, and then sulfonated with chlorosulfonic acid.1 The films were immersed in exess Pt soluion and reduced wih NaBH4.2 The plating processes were repeated up to one to five times to control the thickness of the platinum layers. In accordance with the cycle number of plating platinum electrode, the difference in the surface morphology and the cross section of IPMCs were observed by Scanning Electron Microscopy (SEM). The actuation behaviors of IPMCs were measured by the laser displacement meter. Fig.1. The laser displacement meter References 1. N.Walsby, F.Sundholm, J. Polym.
