Carbon Nanotubes for Thin Film Transistor: Fabrication, Properties, and Applications
Figure 7
Schematic drawing of the direct patterning of SWCNTs onto a flexible substrate by Xiong et al [36]. The parylene-C film was disposed by O2 plasma for 30 s to change hydrophobic surface into hydrophilic and defined microchannel by optical lithography. Then dipped the chip into aqueous SWCNT solution and pulled it up slowly with a speed of 0.1 mm/min. Photoresist was removed by acetone after completing dip coating. The flexible parylene-C SWCNT film could be peeled off from the substrate.
