Preparation and characterization of electrospun poly(vinyl alcohol) nanofibers containing platinum or platinum-ruthenium nanoparticles

Anisotropic architecture and electrical stimulation enhance neuron cell behaviour on a tough graphene embedded PVA: alginate fibrous scaffold

“…The absorption peak centering at 846 cm À1 was related to the vibration of the C-H group and two broad peaks covering the range of 1041 and 1093 cm À1 were corresponded to the stretching vibration of the C-O and C-O-C groups. 45 Moreover, pure alginate powder revealed a sharp asymmetric carboxylate band at 1612 cm À1 and a broad hydroxyl band at 3296 cm À1 . 46 The FTIR spectrum of Gr-AP brous scaffolds consisted of both peaks related to PVA and alginate.…”

Preparation and characterization of antimicrobial electrospun poly(vinyl alcohol) nanofibers containing benzyl triethylammonium chloride

“…In addition, the peaks at 849, 1095 and 1143 cm −1 were assigned to C-C-O, C-O and C-C-C stretching, respectively. The peak at 1236 cm −1 was attributed to C-C stretching [62][63][64]. The FT-IR spectra of BTEAC-PVA nanofibers (Fig.…”

Electrospun poly(acrylic acid)/poly(vinyl alcohol) nanofibrous adsorbents for Cu(ii) removal from industrial plating wastewater

“…40,41 The peaks at 822, 1091, and 1237 cm À1 were attributed to C-C-O, C-O, and C-C stretching, respectively. [42][43][44] Bands at 1704 cm À1 and 913 cm À1 were ascribed to a carbonyl group (-CO-O-) of the crosslinked PAA/ PVA and an O-H group of the carboxyl group in PAA, respectively. 45,46 Aer Cu(II) adsorption in synthetic solution and industrial plating wastewater, a new peak appeared at 1617 cm À1 due to the interactions between Cu(II) and carboxyl oxygen on the surfaces of the nanobrous adsorbents.…”
