摘要

Polyvinyl alcohol (PVA)/polyoxotungstoeuropate composite fibres were successfully prepared by a facile method called the electrospinning technique. Scanning electron microscopy (SEM) analysis revealed the fibre morphology of the composite. Transmission electron microscopy (TEM) showed spherical nanoparticles of the polyoxotungstoeuropate component with an average particle size of several nanometres to tens of nanometres and good dispersion. The electrospinning process prevented the polyoxometalate (POM) turning to an inhomogeneous microphase and large aggregation, so it is an effective and facile method for avoiding the phase separation of POM in the polymer matrices. X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and ultraviolet-visible (UV-vis) spectra were used to characterize the structure of PVA/polyoxotungstoeuropate composite fibres. The fluorescence properties of the composite fibres were also investigated.
