摘要

Proton exchange membrane NafionRTM has been studied using current sensing atomic force microscopy to reveal ionic domains and the local ionic conductivity distribution in the membranes. It is found that the local conductivities are not correlated with the surface topography of the membranes. The local ionic conductivity in the membranes shows several peaks, peak position and peak width of the distribution change with relative humidity. The changes are interpreted as due to the increased sizes and organizations of hydrated clusters in the membranes and the tip effect. Analysis of the conductance distribution of Nafion membranes reveals the dimension and distribution of ionic clusters are very important to determine the structure of Nafion.
