Carbon Nanotubes on Carbon Nanofibers: A Novel Structure Based on Electrospun Polymer Nanofibers

Advanced Materials, 2004
Electrospun nanofibers of polyacrylonitrile, containing an iron compound, have been converted to carbon nanofibers, with iron particles on their surfaces. The iron particles catalyze the growth of carbon nanotubes with iron tips (see Figure). A mechanically strong and electrically conducting path exists between each metal particle and the supporting ...

Large-Scale and Selective Synthesis of Carbon Nanofiber Bundles, Curved Carbon Nanofibers and Helical Carbon Nanofibers

Journal of Nanoscience and Nanotechnology, 2015
Through the pyrolysis of acetylene at 250 °C, large quantities of carbon nanofiber bundles (CNFBs), curved carbon nanofibers (CCNFs) and helical carbon nanofibers (HCNFs) can be synthesized selectively by controlling the Fe:Cu molar ratio of Fe-Cu nanoparticles.

Continuous Carbon Nanofibers For Nanofiber Composites

MRS Proceedings, 2001
ABSTRACTContinuous carbon nanofibers were manufactured using electrospinning technique. The as-spun polyacrylonitrile (PAN) nanofibers were stabilized and carbonized to convert them into carbon nanofibers. The diameters of typical carbon nanofibers were in the range from 100 -500 nanometers.
