Highly conducting and flexible few-walled carbon nanotube thin film |
| 초록 |
We report an effective route to prepare highly conducting and flexible few-walled carbon nanotube (FWNT) thin films. The free-standing thin films were fabricated by functionalizing FWNTs with 4-ethoxybenzoic acid (EBA) via a direct Friedel-Crafts acylation reaction in a non-destructive PPA/P2O5 medium. EBA-f-FWNT thin films were formed by a simple suction filtration of the dispersed solution. Electron microscopic studies were employed to characterize the morphologies of the resulting thin films. The obtained results indicate that the structure of FWNTs was not perturbed by the incorporation of EBA moieties, which were uniformly grafted onto FWNT forming the FWNT networks. Room temperature electrical conductivity of the thin films obtained using standard four probe measurements which revealed a value as high as 29,400 S m-1, while the tensile strength and modulus of the film was found to be about 80 MPa and 15 GPa respectively. |
