In this study, we investigated the mechanical properties of various type ionic polymer-metal composites (IPMCs) and Pt,
Au, Pd, and Pt electroded ionic liquid (IL-Pt) IPMCs, by testing tensile modulus and dynamic mechanical behavior. The
SEM was utilized to investigate the characteristics of the doped electroding layer, and the DSC was probed in order to
look into the thermal behavior of various types of IPMCs. Au IPMCs, having a 5~7 &mgr;m doped layer and nano-sized Au
particles (ca. 10 nm), showed the highest tensile strength (56 MPa) and modulus (602 MPa) in a dried condition. In a
thermal behavior, Au IPMC has the highest Tg (153°C) and Tm (263°C) in both the DMA and DSC results. The fracture
behavior of various types IPMCs followed base material's behavior, NafionTM, which is represented as the
semicrystalline polymer characteristic.
