摘要：

Solid polymer electrolyte films blended with ionic liquid 1-ethyl-3-methylimidazolium tricyanomethanide (EMImTCM) and poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) are prepared via solution cast technique. The physical characterization of polymeric film is performed by X-ray diffraction (XRD), polarized optical microscopy (POM), Fourier transform infrared spectroscopy (FTIR), and thermo-gravimetric analysis (TGA) studies. The gel electrolyte film with 300 wt% of IL shows the high ionic conductivity value of 3.7 x 10(-2) S cm(-1), and operating voltage from -0.5 to 1.5 V, i.e., electrochemical stability window (ESW) approximate to 2.0 V. The dielectric properties of the polymeric films such as dielectric constant, dielectric loss tangent (Tan delta), relaxation frequency, and time are evaluated.
