Many of applications for carbon-based electronics have been required the integration of SWNTs into ordered macroscopic structures in a controlled way. however, it is still a challenge to fabricate large scale, highly organized SWNTs onto solid substrates. Here we describe a reliable method for generating aligned, patterned SWNT structures over large areas using the Langmuir-Blodgett (LB) technique. We synthesized thiophenol-modified SWNTs (SWNT-SH). The resulting SWNT-SHs were found to be soluble in chloroform, which allowed the nanotubes to form a stable monolayer at the water/air interface. We found that the compression of SWNT-SHs on a LB trough leaded to a uniform SWNT-SH monolayer, where SWNT-SHs were aligned parallel to the trough barrier. In addition, we have achieved the formation of well-defined, patterned SWNT-SH arrays using both of microcontact printing and the LB technique. |
