The multi-fields responsive ionic polymer-metal composites, which have wide applications such as actuators, sensors and dampers in one body, are synthesized through an in-situ standard ion-exchange method using Ni particles doped on a NafionTM film. SEM, EDS, and XRD were utilized for revealing their crystal shape and type. Also dynamic mechanical analysis, vibrating sample magnetometry, and cyclic voltammetry were used to investigate the mechanical, magnetic, and electrical properties of the Ni doped ionic polymer-metal composites. The nano-sized Ni particles (ca. 300 nm) were synthesized on the NafionTM film with 2.5 μm layer. The Ni doped ionic polymer-metal composites demonstrated good magnetic, electric and electro-mechanical responses.
