A nanofibre composed of carbon.

OBS

A nanofibre is a nano-object with two similar external dimensions in the nanoscale and the third dimension significantly larger.

Nanofibre composée de carbone.

CONT

Les scientifiques travaillant sur le projet HARCANA («High aspect ratio carbon-based nanocomposites») financé par l'UE ont examiné l'une des classes de nanomatériaux les plus étudiées, les nanoparticules de carbone (NPC). Les NPC comprennent les nanotubes de carbone (NTC), les nano-fibres de carbone (NFC) et les nano-feuillets de carbone («carbon nanosheets» - CNS) ou graphite exfolié. L'introduction des NPC dans les polymères en tant que remplisseurs (nanoremplisseurs) pour produire des nanocomposites constitue un domaine de recherche actif. L'une des principales difficultés techniques dans ce domaine concerne l'agglomération ou l'encastrement. Comme mentionné précédemment, cela peut modifier considérablement les propriétés.

OBS

On entend par «nanofibre» un nano-objet dont deux dimensions externes similaires sont à la nano-échelle et dont la troisième dimension est significativement plus grande.

DEF

A carbon nanotube composed of stacked truncated graphene nanocones.

CONT

Cup-stacked carbon nanotubes (CSCNTs) differ from other quasi-1D carbon structures, which normally behave as quasi-metallic conductors of electrons. CSCNTs exhibit semiconducting behaviors due to the stacking microstructure of graphene layers.

CONT

While carbon nanotubes (CNT) and carbon nanofibers (CNF) are both hollow, nanometer in scale, and produced in a similar manner, there are distinct differences which significantly impact their performance and ability to be processed. The primary differences between the materials are morphology, size, ease of processing, and price. Carbon nanofibers, also known as Stacked-Cup Carbon Nanotubes (SCCNT), have a unique morphology in that graphene planes are canted from the fiber axis, resulting in exposed edge planes on the interior and exterior surfaces of the fiber. CNTs, on the other hand, typically resemble an assembly of concentric cylinders of graphene. To illustrate the difference in morphology, Figure 1 ... shows a side by side comparison of A) multi-walled carbon nanotubes [MWCNT] and B) stacked-cup carbon nanotubes. ... Figure 1. A) Multi-wall CNTs are composed of concentric cylinders of graphene where the basal planes form an inert surface. B) The stacked-cup structure of CNF has exposed graphitic edge planes along its length, providing opportunities for chemical modification of the surface for covalent bonding directly with the matrix.

OBS

This is completely different from single-wall or multiwall carbon nanotubes in structure. The open top and bottom edges of truncated graphene nanocones appear on the inner and outer surfaces of the nanotube, respectively.
