of poly(ethylene oxide)–LiOTf electrolyte films
were prepared using a variety of hydrocarbon templates as nanofillers,
resulting in observable nanophase separation in the polymer electrolyte.
Upon partial extraction of the nanofiller template, an enhanced conductivity
over 2 orders of magnitude was measured using ac impedance. Scanning
electron microscopy, differential scanning calorimetry, and thermogravimetric
analysis were employed to characterize the porosity, composition,
and mass loss of template-extracted and nonextracted film samples.
