Abstract
In this paper we present a study of ionic conductivity versus salt fraction for PEO-NH4ClO4 films. Films with salt concentration x in the range 0 – 0.35 (x is the weight fraction of the salt) were prepared for the study. X-ray diffraction and differential scanning calorimetry were done to detect the different species present and to estimate the crystallinity of the films. The films have a wide variety of structures and exhibit a transformation from fractal to nonfractal morphology as x is increased. We attempt a correlation of ionic conductivity with crystallinity and morphology of films with varying x and find that the fractal to compact crossover region has the highest ionic conductivity.
