| 摘 要： | Aligned carbon nanotubes (CNTs) wre prepared on Ni-coated Ni substrate by microwave plasma chemical vapor deposition (MWPCV D) with a mixture of methane and hydrogen gases at temperature of 550℃ . The experimentul results show a direct correlation between the alignment of CNTs and the density of the catalyst particles at low, temperature, When the particle density is high enough, among CNTs there are strong interactions that can inhibit CNTs from growing randomly. The crowding effect among dense CNTs results in the aligned growth of CNTs at low temperature.

| Abstract: | Aligned carbon nanotubes (CNTs) were prepared on Nicoated Ni substrate by microwave plasma chemical vapor deposition (MWPCVD) with a mixture of methane and hydrogen gases at temperature of 550°C. The experimental results show a direct correlation between the alignment of CNTs and the density of the catalyst particles at low temperature. When the particle density is high enough, among CNTs there are strong interactions that can inhibit CNTs from growing randomly. The crowding effect among dense CNTs results in the aligned growth of CNTs at low temperature.
