Stokes–Einstein–Nernst Relation in Dilute Electrolyte Solutions of Lithium Perchlorate in Polyethylene Glycols (200, 300, 400, and 600)

The electrical conductivity was measured for dilute electrolyte solutions of lithium perchlorate (LiClO4) in polyethylene glycols (PEG) of different molecular weights (200–600). The results were interpreted in the frame of the Stokes–Einstein–Nernst model. It was found (i) a breakdown of the model in the glycol-based polymeric matrices used and (ii) an increase of the deviation from the model predictions with increasing molecular weight of the matrix. The role of the flexibility of HO–[CH2–CH2–O]n–H chains in the efficiency of charge carriers transport in liquid glycols is discussed.
