Paper Abstract

The cast and electro-spun membranes of EVOH-g-nSPEG were prepared by solution cast method and electro-spun method respectively. The cast membrane Ionomer/Metal composites (IPMC) and electro-spun membrane IPMC were prepared by penetration-reduction process. The micro-morphology of these two IPMCs was studied by scanning electron microscope (SEM). The surface resistance (RS) and critical response voltage (UR) of IPMC electrode were tested and calculated by four electrode structure method and intercept method. And the bending stress of IPMC was tested by electro-deformation experiment. The results indicated that the surface of cast membrane IPMC had better smoothness and compactness than that of electro-spun one. The electro-spun membrane possessed compact surface and loose internal structure. The UR for electro-spun membrane IPMC was lower than that of cast one. And the UR for both IPMCs increased with the RS increasing when tested with the same membrane structure and metal electrode. The cast membrane IPMC had higher bending stress with the maximum value being 4.75MPa while being only 0.66MPa for electro-spun membranes.
