Glassy carbon nanofibers from electrospun cellulose nanofiber
Journal of Materials Science, 2014Glassy carbon nanofibers (g-CNFs) with diameter of ca. 45 nm were prepared from electrospun cellulose nanofibers (CelluNFs) by two sequential steps: stabilization and carbonization. The CelluNFs were stabilized at 400 °C and carbonized at 850 and 1400 °C to produce g-CNFs.

Polycarbonate carbon nanofiber composites
European Polymer Journal, 2005Carbon nanofiber (CNF) composites have the potential for creating inexpensive, semiconducting polymers. These composites require a homogeneous dispersion within the polymer. Many groups have focused on high shear methods such as twin screw extrusion.

Characteristics of Carbon Nanofibers
2020Carbon 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, 1992Recently 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 ...

Zirconia/carbon nanofiber composite
Scripta Materialia, 2008The effect of the addition of carbon nanofibers (CNFs) on the microstructure, fracture/mechanical and electrical properties of the CNF/zirconia composite has been investigated. The microstructure of both ZrO 2 and ZrO 2 –CNF composites consists of a very low grain sized matrix (approximately 160 nm) with relatively well dispersed carbon nanofibers in ...

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.

Silk Nanofibers/Carbon Nanotube Conductive Aerogel
Macromolecular Rapid CommunicationsAbstractNatural silk nanofibers (SNF) are attractive conductive substrates due to their high aspect ratio, outstanding mechanical strength, excellent biocompatibility, and controllable degradability. However, the inherently non‐conductivity severely restricts the potential sensor application of SNF‐based aerogels.
