Fig. 5From: Novel ultra-stretchable and self-healing crosslinked poly (ethylene oxide)-cationic guar gum hydrogelFTIR spectra. The dashed boxes represent the four main regions analyzed for the functional group vibrations in raw materials and in HGs. From left to right: O–H, C-H, the cationic polymer region of CGG, and C-O and C–O–C stretching vibrationsBack to article page
