| Abstract: | Polyacrylonitrile/carbon nanotube(MWCNTs/PAN) composite microspheres were prepared by aqueous deposition polymerization.Prior to the fabrication of composites,the MWCNTs were functionalized with Fenton reagent.Electrospinning of f-MWCNTs/PAN composite solution was investigated to fabricate ultrafine fibers.The morphology and thermal stability of fibers were characterized by scanning electron microscope(SEM) and thermogravimetric analysis(TGA),the relationship between the tensile properties and the mass fraction of MWCNTs in the fiber was revealed by tensile testing.The results show that functionalized MWCNTs are well dispersed in polyacrylonitrile matrix with reinforced composite fibers resulted.Furthermore,the tensile strength and elongation at break of the functionalized MWCNTs/PAN composite fiber membranes are higher than that of pure MWCNTs/PAN composite fiber membranes and pure PAN fiber membranes. |
