Synthesis and fabrication of silver nanowires embedded in PVP fibers by near-field electrospinning process

Flexible conductive Ag nanowire/cellulose nanofibril hybrid nanopaper for strain and temperature sensing applications

“…As shown in Fig. 1e, pure PVP shows the basic functional groups of PVP listed as follows: the peak at 3408 cm À1 corresponds to the stretching vibration of -OH group; the peak at 2952 cm À1 is assigned to the stretching vibration of -C-H group; the peaks at 2913 and 2890 cm À1 represent the symmetric and asymmetric stretching vibrations of -CH 2group, respectively; the peak at 1647 cm À1 is ascribed to the stretching vibration of -C@O group [55]. As for the spectrum of as-prepared AgNW, all the typical peaks of PVP are also observed.…”

Fabrication of patterned polymer-antibiotic composite fibers via electrohydrodynamic (EHD) printing

“…While several articles report direct writing of PEO fibers (resolution ~200 nm) [37] and the near field ES of PVP/AgNWs fibers (resolution ~500 nm to10µm) [50], to the best of our knowledge there are no studies, M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 4 which detail PVP/PEO composite fiber patterning by EHDP for drug delivery. The release of active drug from polymeric structures generated using EHDP is scarce in general, but is highly valuable to coincide with exciting developments in the manufacturing of pharmaceuticals via printing [51].…”

Synthesis of TiO2/WO3 Composite Nanofibers by a Water-Based Electrospinning Process and Their Application in Photocatalysis

“…C-O and C-N stretching bands of PVP can be seen in the range 1250-1220 cm −1 . Stretching and bending vibrations of C=C can be seen at 1550 cm −1 and 980 cm −1 , respectively [28]. Peaks at around 700-900 cm −1 can be attributed to W-O vibrations.…”
