Manipulation of single walled carbon nanotube droplets

Abstract

Carbon nanotubes have attracted great attention as future electronic and mechanical materials. However, manipulating techniques are not well developed yet. We propose to use electrostatic drop-on-demand devices to eject micro-droplets of micelle-suspended single walled carbon nanotubes. A simple electrostatic force analysis and photographic studies of droplet ejection process are presented. The analysis shows that semiconducting species have higher electrostatic force density. However, the enrichment of specific electronic types is not clear at large size droplets produced in this study. A micro-scale jetting device is being produced to prove the suggested behavior.
