“…Furthermore, two peaks of Cd 3d are observed at 411⋅7 and 405⋅2 eV (shown as panel B), which are related to the binding energies of 3d 3/2 and 3d 5/2 of Cd, respectively. This result is in agreement with previous reports by Lu et al (2005b). In addition, the line a in panel C indicates a peak of N 1s at 402⋅3 eV in CTAB.…”

The major objective of this work was to detect the change of photoluminescence (PL) intensity of CdTe nanoparticles (NPs) before and after transfer from liquid phase to polystyrene (PS) matrix by electrospinning technique. Thio-stabilized CdTe NPs were first synthesized in aqueous, then enwrapped by cetyltrimethylammonium bromide (CTAB), and finally, transferred into PS matrix to form CdTe/PS nanofibres by electrospinning. Then, CdTe/PS nanofibres were characterized by scanning electron microscope (SEM) and transmission electron microscope (TEM) to observe their morphology and distribution, respectively. The selective area electronic diffraction (SAED) pattern proved that the CdTe NPs were cubic lattice. The PL spectrum indicated that CdTe NPs have been transferred into PS nanofibres, and the PL intensity of CdTe NPs in the nanofibres was even higher than that before CdTe NPs were introduced into PS nanofibres. Moreover, X-ray photoelectron spectra (XPS) revealed that thiol-stabilized CdTe NPs were enwrapped by CTAB, and PS acted as a dispersant in the process of electrospinning.

“…The incorporation of Ag NPs into a nanofibrous structure is an attractive method, because Ag NPs distributed evenly in a nanofibrous structure can be used in novel specific applications, in catalysis, sensors, photonics, and electronics [8][9][10][11][12]. Poly(vinyl alcohol) (PVA) is a water-soluble, nontoxic, biocompatible and biodegradable synthetic polymer.…”

Ag nanoparticles (NPs) were prepared by chemical reduction based on green synthesis in an aqueous poly(vinyl alcohol) (PVA) solution with different temperatures and pHs. The PVA and maltose were used as stabilizing and reducing agents, respectively. Silver nitrate (AgNO 3 ) precursor for Ag NPs was also used by 1 wt% on the base of the weight of PVA. The formation of Ag NPs was examined by UV-Vis spectrophotometer, and their size was measured by transmission electron microscopy (TEM), and nanoparticle size analyzer (NPSA). The formation rate of Ag NPs in the PVA solution increased with increasing temperature and pH, whereas the size of Ag NPs stabilized with PVA increased with increasing temperature, or with decreasing pH. Subsequently, the PVA nanofibrous matrix containing Ag NPs was prepared, by electrospinning PVA solution with Ag NPs, and followed by heat treatment. The morphology and crystalline structure of PVA nanofibers with Ag NPs was observed with field emission scanning electron microscopy (FE-SEM), and X-ray diffractometer (XRD), respectively. From the degradation reaction of methylene blue (MB) using PVA nanofibers web and film, it was found that the catalytic activity of PVA matrices with Ag NPs was strongly dependent on the surface area of the PVA matrices.

Abstract. Rubber composite fibers containing silver nanoparticles with high morphological stability were prepared through combination of electrospinning and in-situ chemical crosslinking. The composite fibers included those of Ag/polybutadiene rubber (BR), Ag/polyisobutylene-isoprene rubber (IIR), and Ag/silicon rubber (SiR). During the study, Ag nanoparticles (Ag NPs) were first generated through reducing the Ag + ions in rubber/N,N-dimethyformamide/tetrahydrofuran solutions upon ultraviolet-irradiation; subsequently, rubber composite fibers with uniform diameters from hundreds of nanometers to several micrometers were made by electrospinning the above solutions. The electrospinning was carried out with in-situ chemical crosslinking. The results indicated that chemical crosslinking during (and shortly after) electrospinning was able to improve substantially the morphological stability of rubber fibers. As indicated by the results acquired from UV absorption spectroscopy, X-ray photoelectron spectroscopy and transmission electron microscope, Ag nanoparticles with sizes of 10~20 nm were uniformly dispersed in rubber fibers. It was believed that, in addition to the protection of polyvinyl pyrrolidone, a rapid solvent evaporation and limited motion space for a very fine fiber during electrospinning could prevent/mitigate the aggregation of Ag NPs, resulting in a very uniform dispersion. The electrospun Ag NPs/BR composite fibers made of the solution containing very low loading amount (3 wt%) of AgNO 3 demonstrated strong antimicrobial activity.
