文摘

A new gel polymer electrolytes composed of poly(vinylidene chloride-co-acrylonitrile) (PVdC-co-AN) co-polymer and plastic crystal succinonitrile (SN) were prepared to form plastic crystal gel polymer electrolytes (PGPEs) with the variation of magnesium triflate (MgTf₂) salt from 5 to 30 wt.%. The room temperature and temperature dependence studies of the PGPE films were determined by using AC impedance spectroscopy. The conductivity versus reciprocal temperature plot has shown a nonlinear behavior. The ionic and cationic transport numbers were evaluated by DC polarization method and the combination of DC polarization and AC impedance methods, respectively to determine the charge carrier species in the PGPE films. To study the interactions among the constituents in the PGPEs as well as to confirm the complexation between them, Fourier transform infrared spectroscopy (FTIR) was carried out. The analysis of FTIR spectra was further investigated by deconvolution of the FTIR spectra to prove the dependability of ionic conductivity and transport number with the presence of free ions, ion pairs, and ion aggregates in the PGPEs.
