WebThe FTIR spectra of the sulfonated PVdF (S-PVdF) are shown in Fig. S2. The predominant peaks in the region of the 1035 and 1277 cm −1 (symmetric and asymmetric stretching of O=S=O), and 1012 cm −1 (S=O stretching) are for sulfonate groups [20, 21]. The 1 H NMR spectroscopy was also used to confirm the sulfonation of PVdF, as seen in Fig. S3.
