제목 Effects of Supercritical Fluids on CNT Dispersion
초록  Electrical conductivity of carbon nanotubes (CNTs) is useful in developing conducting paste and transparent conducting coating. However their success in the market place currently somewhat hindered by lack of their dispersion stability in solutions or pastes due to the aggregation of CNTs resulting mainly from van der Waals interaction.  
 Ultra-sonication is normally applied to CNTs in order to enhance dispersibility of CNTs, which, however, usually introduce defects on them resulting in electrical conductivity reduction. To overcome these disadvantages and minimize damages on CNTs during ultra-sonication, in this study we report that damages from ultrasonic treatment on CNT are greatly reduced while dispersion is enhanced by supercritical fluids (SCFs) treatments. Raman spectroscopy and Dynamic Light scattering studies will confirm the effects of SCF on CNT treatments.
