Preparation and characterization of PA 6?/organical montmorillonite composite nanofibers

Composite nanofibers of PA 6 and organically modified montmorillonite (O-MMT),DK-5,were prepared by electrospinning.The dispersion and exfoliation of O-MMT were obtained by two steps: the primary exfoliation in DMF and the further exfoliation in PA 6 solution.The size distribution of O-MMT layers was measured in a particle size analyzer and the fibrous structures of the composite nanofiber were examined using SEM.An AFM in tapping mode was employed to investigate the surface morphology of the electrospun nanofibers.The study has revealed that the dosage of O-MMT has impact on the morphology and structure of the composite nanofiber.
