Highly Dispersible Carbon Nanotubes via Graphene Quantum Dots for Electrical Dissipation-Free and Transparent Conducting Films |
| 초록 |
Carbon nanotubes are one of the most promising nanomaterials owing to their good structural properties, such as high aspect ratio and sp2 carbon conjugated network. Especially, outstanding electrical properties have attracted much attention for application in opto-electronic devices. To maximize the effect of CNT in a solution and polymer matrix, CNT should be well-dispersed in solvents and matrices with low fraction of CNT. Mostly, organic surfactants have been employed as a dispersants to improve the dispersion CNTs. Thus, we carefully investigated the effect of graphene quantum dots as a surfactant for dispersion of CNTs in the ethanol. We characterized the electric conductivity of GQD assisted CNT dispersion compared to the well-known common organic surfactants, namely SDS, PVP. As the results, GQDs can be used as the surfactant to highly dispersible CNT and their films showed excellent electrical properties compared to organic surfactants. |
