Abstract
Multiwalled carbon nanotube (MWCNT) filaments were grown by catalytic chemical vapor deposition on 2-D weave carbon fiber (CF) cloth substrates. Two different sets of experiments were carried out to understand the growth mechanism of these filaments. In the first set of experiments where CF cloths were coated with the catalysts particles, CNT filaments having long length (>200 μm) and large diameter (15–25 μm) were obtained. In another set of experiment, where CF cloths without catalyst particles were used, only MWCNTs without any filament formation were obtained. On the basis of the results, a growth mechanism has been proposed. These MWCNT filaments can be used for preparing CNTs reinforced polymer composites having very good structural properties, which are being sought after.
Highlights
Carbon nanotube (CNT), a fascinating material with outstanding properties has inspired the scientist, engineer and technologist because of its wide range of potential applications (Ajayan and Zhou 2000) in many areas
When the desired temperature (750 °C) was reached, nucleation of the CNTs occured in the catalyst clusters and CNT filament formation started
Multiwalled carbon nanotube (MWCNT) were synthesized on carbon fiber (CF) cloth by two different methods and for growth times (1 and 2 h)
