Abstract: In this paper, polyacrylonitrile/zinc acetate (PAN/Zn(Ac)2) composite nanofibers were produced by electrospinning. After stabilization and carbonization, carbon/zinc oxide (CNFs/ZnO) composite nanofibers were made. Various nanofiber membranes were characterized by SEM, FT-IR, TEM, EDS and SZT-2 automatic four-point probe tester. The results revealed that to obtain desirable CNFs/ZnO composite nanofibers, PAN/Zn(Ac)2 composite nanofibers were stabilized at 270℃ for 2h and carbonized at 800℃ for 1h. The diameters of CNFs/ZnO composite nanofibers were less than the corresponding PAN/Zn(Ac)2 composite nanofibers; The thermostability of CNFs was improved by adding acetate zinc into spinning solution; ZnO nanoparticles dispersed well on the surface and inside of the CNFs; the electrical resistivity of CNFs/ZnO composite nanofibers were higher than pure carbon nanofibers, and with the increase of the ZnO content the electrical resistivity of CNFs/ZnO composite nanofibers also increased.
