Horizontal Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy
(HATR-FTIR) and Differential Scanning Calorimetry (DSC) have been employed to study the correlation
between the concentration of lithium trifluoromethanesulfonate (LiTf) salt with the conversion of
crystalline to amorphous nature in poly(vinylidene fluoride-co-hexafluoropropylene) [P(VdF-HFP)].
