Preparation and Characterization of Aligned Carbon Nanotube Fibers

Abstract

High-quality carbon nanotube (CNT) arrays have been synthesized through a chemical vapor deposition process. The Fe/Al2O3 on silicon was used as the catalyst, ethylene as the carbon source, and a mixture gas of Ar and H2 gases as the carrying gas. With spinnable CNT arrary as initial materials, aligned carbon nanotube fibers were continuously fabricated by dry spinning. And then we study the excellent mechanical property of the carbon nanotube fibers.
