Due to good alignment,excellent electrical and thermal conductivity,high surface area, and high carbon purity,vertically-aligned carbon nanotube (VACNT) forests have shown to be advantageous for numerous applications. This paper summarizes recent advances in several chemical vapor deposition (CVD) methods for synthesizing VACNT forests. It focuses on kinetics and termination mechanism of VACNT forest growth by the CVD technique,and catalyst morphology evolution was designated to be the main reason for termination of CNT forest growth. In addition,the progress in structure tailoring of VACNTs (including wall number,diameter and density) through condition control and catalyst designing are also introduced. And,massive growth of VACNT forests and precise control of their structure are regarded as important points to be further studied in the future.
