Self-Organized Grafting of Carbon Nanotubes by End-Functionalized Polymers |
| 초록 |
Carbon nanotubes have outstanding physical and chemical properties due to their idealized one-dimensional structure consisting of sp2 hybridized carbons. The practical utilization of superior properties of individual nanotubes, however, has been limited by the bundling of nanotubes, which originates from strong tube-tube interaction. In order to utilize the superior properties of individual carbon nanotubes, we introduce a facile and robust self-organized functionalization method for carbon nanotubes utilizing end-functionalized polymers. Various polymers end-functionalized by terminal groups such as amines, hydroxyl or carboxylic acid groups are spontaneously grafted to the carbon nanotubes through a simple solution mixing process. The noncovalent functionalization enhances the dispersibility of carbon nanotubes in organic solvent and polymer matrix. |
