Rheology of carbon nanofiber-reinforced polypropylene
Rheologica Acta, 2008The rheological properties of two different nanocomposite systems consisting in the dispersion of carbon nanofibers (CNFs) in polypropylene are investigated. The nanoreinforced systems were identically prepared with two CNFs that differ only in the length of the fibers being otherwise identical to analyze the effect of fiber aspect ratio.

Consolidation of carbon nanofibers with pyrolytic carbon
Solid Fuel Chemistry, 2007A strategy of industrial-scale manufacture for a wide range of carbon materials based on carbon nanofibers is proposed. It was shown that porous materials with a high sorption capacity can be obtained with the use of carbon nanofibers by means of conventional manufacturing operations.

Carbon Nanotubes on Carbon Nanofibers: A Novel Structure Based on Electrospun Polymer Nanofibers
Advanced Materials, 2004Electrospun 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 ...

Emerging Carbon-Nanofiber Aerogels: Chemosynthesis versus Biosynthesis.
Angewandte Chemie, 2018Carbon aerogels that are typically prepared using sol-gel chemistry have unique three dimensional networks of interconnected nanometer-sized particles and thus exhibit many fascinating physical properties and great application potentials in widespread ...

This paper reports the effect of the conditions of stabilization process on the properties of special polyacrylonitrile nanofibers (SAF) with an average diameter of 467 nm. Stabilization constitutes an important pretreatment for the production of either carbon fibers or activated carbon fibers. It was found that the higher the stabilization temperature,

Y-Junction Multibranched Carbon Nanofibers
Journal of Nanoscience and Nanotechnology, 2005Multibranched carbon nanofiber (CNF) is produced by a thermal chemical vapor deposition method using camphor as precursor. Nickel and cobalt catalyst was deposited on silicon substrate by e-beam evaporation and used as substrate for the growth of carbon nanomaterials.

Natural carbon nanofibers in graphite [PDF]
Mineralogy and Petrology, 2011 Natural carbon nanofibers have been found in diamond-bearing carbonatites from the Chagatay trachyte-carbonatite complex (Uzbekistan) and described using a series of methods, including SEM, TEM, and Raman spectroscopy. The carbon nanofibers occur as tight aggregates within the host graphite, forming natural bulk nano-structural intergrowths.

Abstract Conducting glass fiber fabrics (GFs) with double-scale roughness were fabricated by growing carbon nanofibers (CNFs) on its surfaces. The homogeneous growth of CNFs was achieved by the decomposition of C2H2 on glass fibers surfaces coated with Fe-doped mesoporous silica films at different C2H2 flow rates. The chemical composition and surface
