Inversed micelles formed by polystyrene-block-poly(2-vinyl-pyridine) in toluene loaded with FeCl3 were used to synthesize and deliver discrete Fe2O3 nanoclusters with uniform diameters to flat substrates. Single-walled carbon nanotubes (SWNTs) were grown by chemical vapor deposition using these nanoclusters as the catalysts. Atomic force microscope characterizations revealed that high density SWNT mats were grown on the surface and the diameter of nanotubes was controlled by the diameter of nanoclusters. Electrical measurement revealed that the dense SWNT mats contained both semiconducting and metallic SWNTs and could be used to build thin film transistors.
