Fabrication and Applications of Carbon Nanotube Fibers

FABRICATION OF CARBON FIBERS FROM COMMERCIAL WET SPIN POLYACRYLONITRILE FIBERS

Carbon fibers are fabricated from different materials such as special polyacrylonitrile (PAN) fibers, cellulose fibers and pitch. But PAN fibers are recognized as the most widely used precursor for the present-day manufacture of carbon fibers. The process of fabrication carbon fibers from special PAN fibers is composed of two steps including oxidative stabilization at low temperature and carbon...

Nanotube Composite Carbon Fibers

The mechanical properties of materials in small rod-shaped form are of considerable technological interest since, due to their shape and size, they can exhibit appreciably greater strength relative to corresponding macroscopic forms. For example, the mechanical strength of silicon carbide whiskers systematically increases with decreasing whisker diameter over the 100 to 1 micron range. This phe...

An Overview of Fabrication Methods and Applications of Carbon Nanotube Membrane in Environmental Engineering as Hydraulic Microstructures

The main purpose of this article is to study fabrication methods and applications of aligned carbon nanotube (CNT) membranes as a hydraulic microstructure in treatment processes. This paper emphasizes the use of CNTs as membrane in separation processes like water and wastewater treatment because of their exclusive advantages. Their most important characteristics are high mechanical strength aga...

Strong carbon-nanotube fibers spun from long carbon-nanotube arrays.

The superior mechanical properties of carbon nanotubes (CNTs) mean they have been regarded as a new material with the potential to revolutionize and enable many advanced technologies. CNTs have extremely high tensile strength ( 150 GPa), high modulus ( 1 TPa), large aspect ratio, low density, good chemical and environmental stability, and high thermal and electrical conductivity. These superior...
