摘要：

Poly(ethyl methacrylate) (PEMA)-lithium trifluoromethanesulfonate (LiCF3SO3) polymer electrolytes were prepared using solution casting technique. The interactions between PEMA and LiCF3SO3 were investigated using Fourier Transform Infrared Spectroscopy (FTIR). LiCF3SO3 interacted with PEMA to form a PEMA-salt complex that results in the shifting of the C=O and C-O-C bands to lower wavenumbers. The room temperature ionic conductivity of the polymer electrolyte increased from 2.7 x 10(-9) S cm(-1) to 7.2 x 10(-8) S cm(-1) at 20 wt.% of LiCF3SO3. Deconvolution of spectra band in the nu(s)(SO3-) mode of LiCF3SO3 has been carried out to estimate the spectroscopically free form of CF3SO3-. The finding is in good agreement with the conductivity results.
