Preparation and characterization of carbon nanofibers containing Fe

A mixture of polyacrylonitrile (PAN) and polyferrocenylmethoxylmethylsilanes (PFMMS) in N, N-dimethylformamide and tetrahydrofuran was electronspun into submicrometer fibers with a microphase-separated structure. The fiber precursors were stabilized, and then carbonized. The morphology, size and components of pyrolyzed fibers were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (SEM-EDS) and X-ray photoelectron spectroscopy (XPS).
