Fabrication of Ultra-fine Metal Oxide Decorated Carbon Nanofibers for DMMP Sensor Application |
| 초록 |
Ultrafine metal oxide-decorated hybrid carbon nanofibers (CNFs) were fabricated by a singlenozzle co-electrospinning process using a phase-separated mixed polymer composite solution and heat treatment. Ultrafine hybrid CNFs were then formed by decomposing the PVP phase and transforming the PAN to CNFs of ca. 40 nm diameter during heat treatment. These ultrafine hybrid CNFs were applied to a dimethyl methylphosphonate (DMMP) chemical sensor at room temperature with excellent sensitivity. This is because the metal oxide nanonodules of hybrid CNFs increase the surface area and affinity to DMMP vapor. Our new synthetic methodology promises to be an effective approach to fabricating hybrid CNF/inorganic nanostructures for future sensing technologies. |
