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.

Characteristics of Carbon Nanofibers

2020
Carbon nanofibers (CNFs) are fibrous nanostructures of sp2-hybridized carbon having partial structural similarity with carbon nanotubes (CNTs). This chapter reviews the structure, synthesis techniques, properties and applications of CNFs. CNFs can be produced either by vapor phase growth using chemical vapor deposition or by carbonization of pre ...

Formation of carbon nanofibers

The Journal of Physical Chemistry, 1992
Recently 3-1 50-nm-diameter carbon fibers have been discovered which appear to grow spontaneously by deposition from carbon vapor. It is proposed that these structures may be giant fullerenes which have grown by direct insertion into the graphitic network of smaller carbon species (atoms, ‘linear” chains, monocyclic rings, or even smaller fullerenes ...
