The transparent and flexible solid polymer electrolytes (SPEs) were fabricated from polyacrylonitrile‐polyethylene oxide (PAN‐PEO) copolymer which was synthesized by methacrylate‐headed PEO macromonomer and acrylonitrile. The formation of copolymer is confirmed by Fourier‐transform infrared spectroscopy (FTIR) measurements. The ionic conductivity was measured by alternating current (AC) impedance spectroscopy. Ionic conductivity of PAN‐PEO‐LiClO 4 complexes was investigated with various salt concentration, temperatures and molecular weight of PEO ( M n). And the maximum ionic conductivity at room temperature was measured to be 3.54 × 10 −4 S/cm with an [Li + ]/[EO] mole ratio of about 0.1. © 2006 Wiley Periodicals, Inc.
