Abstract

This paper describes the effect of ozone treatment on water dispersibility of micrometer order long multi-walled carbon nanotubes by using simple ozone generation set up. Inverter type neon transformer was used to supply required energy. The dispersed nanotubes suspension was stable for a few months after treatment. Laser Raman Spectroscopy, Fourier Transform Infrared Spectroscopy, and Transmission Electron Miscroscope were used to characterize the resulted nanotubes. Analyzed data revealed that the multi-walled carbon nanotubes were functionalized by oxygen and hydrogen containing groups.
