Single-walled carbon nanotube networks: purification, liquid deposition methods, and morphological control on pattern formation

A solution-based deposition technique has been proposed to allow easily for the fabrication of SWNT thin films via 2D random networks. This simple technique combines controlled evaporative and convective assembly. Moreover, it has been shown to control network density. A systematic study has been performed to gain novel knowledge about SWNT as a possible electronic material for technological applications. The study included factors that have been observed for their influence on SWNT suspension, approaches for optimizing deposition methods, and deposition methods that explored the SWNT density, network morphology, and nanotube placement.
