Abstract
This paper has proposed novel micro-structuring process of CNTs on desired positions by the help of silica particles. In this process, CNTs are previously adsorbed on the silica particles (1μm diameter), and then the CNT-adsorbed particles are self-assembled on a patterned substrate by dip coating. The authors employ both dry and wet processes for CNT-adsorption, in which they are based on chemical vapor deposition (CVD) and electrostatic interaction, respectively. Then CNT-adsorbed particles are self-assembled on a hydrophilic/hydrophobic-patterned substrate. The particles are self-assembled on only the hydrophilic regions. This process allows CNTs to be patterned on a desired position.
