Graphite oxide is a two-dimensional epoxidized form with a sp2-bonded carbon network together with acidic functional groups. Craphite oxide can be prepared easily using the Hummers method and exfoliated to graphene oxide (GO). GO is dispersed easily in polar organic solvents due to a large amount of functional groups on their surface. However, the dispersion behavior of GO in polar organic solvents differ from that of acid treated carbon nanotubes (a-CNT), which has a large number of functional groups. This study examined the difference in dispersion behavior of a-CNT and GO in polar organic solvents. In particular, in ethanol, the difference in the dispersion behaviors between them was quite interesting. |
