FTIR study on the effect of free ions in PMMA/ENR 50 polymer electrolyte system

Ion association and dissociation influences the transport properties in polymer electrolytes. The interaction between PMMA/ENR 50 blend and NH4SCN salt was investigated using Fourier Transform Infrared Spectroscopy (FTIR) and also to determine the effect of ion dissociation and association. Deconvol...

Description
Summary:Ion association and dissociation influences the transport properties in polymer electrolytes. The interaction between PMMA/ENR 50 blend and NH4SCN salt was investigated using Fourier Transform Infrared Spectroscopy (FTIR) and also to determine the effect of ion dissociation and association. Deconvolution of spectra band in the SCN− mode of NH4SCN has been carried out to estimate the spectroscopically free form of SCN−. The variation in the number of available free mobile ions has influenced the variation of dielectric constant of polymer electrolyte blends.
