Figure 1.
(a) Conceptual representation of the process flow of the synthesis of a series of single-walled carbon nanotube (SWCNT) forest with a continuous and wide range of structural properties. Structural control of SWCNT forests was achieved by decoupling the catalyst nanoparticle formation process from the CNT growth process; (b) Schimatic representation of the series of conditions for catalyst formation process. Conditions shown by red/blue arrows (large/low H2 flow rate and low/high temperature) resulted in high/low density and small/large diameter SWCNT forest.
