Poly(ethylene glycol) functionalized with an amino group (PEG-amine) was synthesized and characterized by proton NMR and FTIR spectroscopy. The polymer was complexed with lithium triflate (LiOTf) in varying ratios, and it was found that the composition (PEG-amine)8.0LiOTf exhibited a maximum ionic conductivity of 10−5 S/cm at a temperature of 320 K. Graphite platelets were also dispersed into the polymer matrix, and the resulting nanomaterials were shown to be electrically conductive, with a maximum value of 1 × 103 S/cm when the graphite is present at 50% by mass.
