Аннотация

Poly(acrylonitrile) (PAN) and polyethyl glycol methyl ether (PEGME) blended with lithium perchlorate (LiClO4) as dopant salt and propylene carbonate (PC) as plasticizer are prepared in the form of thin film. Fourier transform infrared studies show the evidence of the complexation between PAN, PEGME, and LiClO4. The maximum conductivity of polymer electrolyte is up to 4.16 mS cm-1 at 90 oC by optimizing the composition of the polymers, salts, and plasticizer, and the temperature dependence of the conductivity of solid polymer electrolyte obeys the Vogel–Tamman–Fulcher (VTF) relationship. X-ray diffraction studies are carried out to reveal that the PAN phase changes from crystalline to amorphous when PEGME concentration increases.
