In the present work, the polyamide6 (PA6) nanofiber and PA6/organophilic?montmorillonites (OMT) composite nanofiber were firstly prepared by a facile?compounding process with electrospinning, and then coated by nano-Fe2O3 using
magnetron sputter technique. The structure, surface morphology and thermal stability?properties were characterized by X-ray diffraction (XRD), Scanning electron?microscope (SEM), Energy dispersive X-ray spectroscopy (EDX), Atomic force
microscope (AFM) and Thermogravimetric analyses (TGA), respectively. It was found?that the OMT layers were well dispersed within the composite nanofiber. The SEM?images showed that the diameters of composite nanofiber were decreased comparing to?the PA6 nanofiber, and the nano-Fe2O3 well coated on the surface of homogeneous and
cylindrical nanofiber. The EDX confirmed the presences of the OMT and nano-Fe2O3?in the fibers. The AFM images showed that there was a remarkable difference in the?surface morphology of composite nanofiber before and after sputter coating. The TGA?analysis indicated the barrier effects of silicate clay layers and catalysis effects of?nano-Fe2O3 improved thermal stability properties of the composite nanofiber.
