Abstract

Aligned carbon nanotube (A-CNT) has been extensively studied due to their high potential in many applications. Despite the fact that catalyst preparation is the key role to grow A-CNTs, the parameter of catalytic chemical vapor deposition (C-CVD) also influences A-CNT growth and its morphologies. This review focused to critically synthesize the published data in scientific report on A-CNT for better understanding the C-CVD parameter governing vertically A-CNT growth. The review will mainly discuss the influence of C-CVD processing temperature, C-CVD processing time, and carbon feedstock in A-CNT growth and its effects on A-CNT morphologies. Challenges and future perspectives in the synthesis of aligned carbon nanotubes have also been discussed.

Keywords: Aligned carbon nanotubes, carbon nanotubes growth parameter, catalytic chemical vapor deposition, supergrowth.
