	Abstract:In this paper, polyacrylonitrile (PAN) nanofibers were prepared by electrospinning and they were modified with hydroxylamine to synthesize amidoxime polyacrylonitrile (AOPAN) chelating nanofibers, which were further applied to adsorb copper and iron ions. The conversion rate of nitrile groups in PAN was calculated by the gravimetric method. The structure and surface morphology of AOPAN nanofibers were characterized by a Fourier transform infrared spectrometer (FTIR) and a scanning electron microscope (SEM), respectively. The adsorption capabilities of Cu2+ and Fe3+ ions onto the AOPAN nanofiber mats were evaluated. FT-IR spectra indicated that nitrile groups in PAN were partly converted into amidoxime groups. SEM examination revealed that there were no any serious cracks or sign of degradation on the surface of PAN nanofibers after chemical modification. The adsorption capacities of both copper and iron ions onto the AOPAN nanofiber mats were much higher than those onto the raw PAN nanofiber mats. The adsorption data of Cu2+ and Fe3+ ions were fitted particularly well with the Langmuir isotherm. The maximal adsorption capacities of Cu2+ and Fe3+ ions reached 215.18 and 221.37 mg/g, respectively.

	Abstract:In this study, conductive metal films of copper (Cu) and silver (Ag) were deposited onto the polyamide 6 nanofiber nonwoven substrates at room temperature. Atomic force microscopy (AFM) and Scanning Electron Microscopy (ESEM) were employed to study the topography and chemical composition of the nanofibers, respectively. The AFM results indicate a significant change in the morphology of the fibers before and after the sputter coating of the metallic film. A full energy dispersive x-ray analysis (EDX) mounted on the SEM was also used to detect the elemental composition of the functional nanofibers. EDX examination reveals the change in the chemical compositions of the nanofiber surfaces. The surface conductivity properties of the fibers were also investigated. The nanofiber nonwovens sputtered with metallic coating showed significant improvement in surface electrical properties.

	Abstract:A considerable attention has focused on hybrid organic–inorganic nanocomposites in recent years. Organic–inorganic hybrids have both the advantages of organic materials, such as light weight, flexibility and good moldability, and inorganic materials, such as high strength, heat stability and chemical resistance. In this work, polyvinyl acetate (PVAc)/titanium dioxide (TiO2) organic-inorganic hybrid was prepared by sol–gel method. Electrospinning technique was used to fabricate PVAc/TiO2 hybrid nanofibers. Scanning Electron Microscopy (SEM) was employed to examine the morphology of the hybrid nanofibers. The mechanical and thermal properties were characterized by Zwick universal material testing machine and thermo gravimetric analyzer (TGA), respectively. The results showed that the mechanical and thermal stability properties were improved with TiO2 filled in the hybrid.
