A novel approach to prepare silver chloride nanoparticles grown on the surface of PAN nanofibre via electrospinning combined with gas–solid reaction

摘要

Well-defined silver chloride nanoparticles grown on the surface of PAN nanofibre were synthesized by electrospinning technology combined with gas–solid reaction. This method can avoid the possibility of the waste of raw material as well as enhance the usage rate of AgNO3. The PAN nanofibre can be recycled easily. X-ray powder diffraction (XRD) shows the presence of crystal AgCl, X-ray photoelectron spectroscopy (XPS) confirm that there are chemical bonds and interaction between the surface modified PAN nanofibre and Ag ions. This will be propitious to prevent nanoparticles from aggregation. Field-emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) gave the direct evidence that AgCl nanoparticles have been dispersed on the surface of PAN nanofibre homogeneously.
