Preparation And Characterization Of Carbon Nanofibers Containing Fe

Functional carbon fibers are important and have a wide range of applications from energy to the aerospace industry, and the carbon nanofibers containing metal become foreland domain of materials science research, So controllable Preparation of carbon nanofibers containing iron is important.In the present work, PAN/Fc nanofibers were prepared by electrospinning using a composite solution of Fc dispersed into 15 Wt.% polyacrylonitrile (PAN) solution in DMF, and a mixture of polyacrylonitrile and polyferrocenylsilanes in N, N-dimethylformamide and tetrahydrofuran were electronspun into submicrometer fibers. The fiber precursors were stabilized, and then carbonized, the carbon nanofibers containing iron were successfully prepared.The electrospinning, stabilization, and carbonization processes were researched. The thermal decomposition of nanofiber precursors were charactered by TGA, and the morphology, size, structure evolution, and components of nanofibers were characterized by SEM, TEM, XPS, FTIR, and Raman. The results show that the diameters of the nanofibers were decreased during the pyrolysis process, Fe were contained in the surface of the PAN/PFMMS fibers and the valence state of Fe changed in the stabilization and carbonization processes.
