Enhancement of Dispersibility of Carbon Nanotubes Using End-Functionalized Polymers |
| 초록 |
Carbon nanotubes have various attractive properties such as high mechanical and thermal properties and tunable electrical conductivity, etc. However the pristine carbon nanotubes are generally not dispersed in organic solvents or polymer matrix due to the strong Van der Waals interaction among them. In order to utilize the superior properties of individual carbon nanotubes, developing a robust strategy to promote the dispersion is critical. Here, we introduce a new dispersion method for carbon nanotubes using end functionalized polymers. End functional groups induced to polystyrene can interact with the surfaces of multi-walled carbon nanotubes. The noncovalent functionalization enhances the dispersibility of carbon nanotubes in organic solvent and polymer matrix. |
