Peptide-Templated Synthesis of Polyaniline Nanotubes |
| 초록 |
We report the synthesis of polyaniline (PANI) nanotubes by using self-assembled peptide nanowires as a template. Here we used diphenylalanine (Phe-Phe or FF) as a building block for the growth of peptide nanowire (PNW). PNW template was prepared by high-temperature solid-phase self-assembly of FF. We found that PANI readily and uniformly coated PNWs, resulting in the formation of PNW/PANI core/shell nanowires. Our results show that PANI grows preferentially along the side-wall of PNWs by specific interaction between PNWs and PANI during the polymerization process. The thickness of PANI coating on PNW could be controlled by varying the reaction time and the number of PANI coatings. On the basis of the results, we could also fabricate hollow PANI nanotubes by selectively removing PNW core from PNW/PANI nanowires. The present study demonstrates that self-assembled peptide nanostructures can be used as a versatile template for the synthesis of functional nanomaterials. |
