“…19,20 Some characteristic bands near 1434 and 1089 cm À1 for HA are due to amide-type -N-H bending and -C-O-Cbending vibrations, respectively 2 and the peak near 1420 cm À1 correspond to the stretching of carboxyl bonds. 21,22 All spectra show PVA characteristic peaks near 2945 cm À1 , 1734 cm À1 , and 1250 cm À1 , relative to alkyl, acetyl, and -C-O groups, respectively. 23,24 The cross-linking was evidenced by the peak at 1700 cm À1 , which is a clear indication of the existence of the -CO-O- (Fig.…”

“…Fourier transform infrared (FTIR) spectra demonstrated that the spectrum of HA‐MnO 2 had not only the characteristic band of MnO 2 at 600 cm −1 (attributed to Mn\O stretching) but also the characteristic band of HA at ≈2900, ≈1612, ≈1410–1058, and ≈613 cm −1 , in comparison with the spectrum of MnO 2 and NaMnO 4 without any modification ( Figure a). The absorption band at ≈1058 cm −1 that is attributed to the linkage stretching of COH was normalized to compare the difference between HA and HA‐MnO 2 . In contrast, the spectrum of HA‐MnO 2 did not show the characteristic band of NaMnO 4 at 896 cm −1 but showed a new band at ≈1670 cm −1 , which could be assigned to the CO stretch of permanganate oxidation of hyaluronic acid .…”

“…Due to its high cost, HA can be combined with different polymers to reduce its price and improve its physicochemical and biological properties. The incorporation of HA on films based on blends to wound dressing application is justified due to the polymer improve the proliferation, differentiation and migration of cells during the regeneration and healing of tissues [14][15][16][17]. The blend system of polyvinyl alcohol (PVA) and HA has been reported to be a promising material for biomedical application [16,18,19].…”
