Preparation and growth mechanism of fast growing macroscopical long aligned carbon nanotube arrays
摘要
Abstract
The macroscopical long aligned carbon nanotube arrays( ACNTs) with a thickness of 2. 7 mm were prepared by the pyrolysis of organometallic mixtures in 100 min using ferrocene and xylene as catalyzer and carbon source. Using a chemical vapor deposited with no template, the grow rate reached 27 μm · min-1. This process was carried out in a single-furnace system. The products were characterized by scanning electron microscopy (SEM) , transmission electron microscopy (TEM) and Raman spectroscopy. The results indicate that ACNTs have good alignment and fine graphite form. Both the optimized process parameters and the formation mechanism of fast growing macroscopical long ACNTs were summarized. A formation mechanism which the catalyst remains stable and the open ends was adopted, the rapid growth of long carbon nanotube arrays was ensured by continuous supply of carbon source and catalyst.关键词
