摘要：

Room-temperature area mapping of polymer electrolyte films at the nanoscale reveals considerable heterogeneity, with the positional ionic conductivity varying up to four orders of magnitude. Measurements indicate the presence of a bimodal conductivity distribution (see Figure), with highly conducting regions being amorphous but non-percolating at room temperature.
