Research Abstract

Efficiency of water-solubilization of carbon nanotubes (CNT) using pulsed power technology was investigated. The efficiency depended on the pH and conductivity of the suspension. The CNTs were highly solubilized by a streamer discharge in under the basic condition of suspension and those effectively enhanced the streamer discharge phenomenon. Application of the water-solubilized CNTs to composite material was also performed.
