Carbon Nanotube Arrays for Thermal Management Applications

Abstract

The work was designed towards creating aligned multiwalled carbon nanotube arrays by chemical vapor deposition (CVD) of xylene hydrocarbon precursor and simultaneous vapor phase delivery of catalyst particles. Low density nanotube arrays as well as highly dense pyrolitic carbon coated nanotube arrays were produced. The nanotube arrays could be grown to several hundreds of microns long. The simultaneous growth of nanotubes and densification of the aligned carbon nanotube (ACNT) films by carbon infiltration in the interstitial spaces between nanotubes were accomplished in a single step by the combination of the chemical vapor deposition and chemical vapor infiltration processes.
