Enhanced Thermoelectric Properties of Wire-Bar-Coated SWCNT/P3HT Thin Films |
| 초록 |
The influence of processing conditions, such as coating method and ink concentration, on the thermoelectric properties of SWCNT/P3HT nanocomposite films was systematically investigated. Using simple wire-bar-coating, SWCNT/P3HT nanocomposite films could be obtained. They showed high thermoelectric properties without additional P3HT doping process. The wire-bar-coated SWCNT/P3HT nanocomposite films exhibited power factors of up to 105 μW m−1 K−2 at room temperature. The SWCNT bundles with diameters in the range of 6−23 nm formed an interconnected network in the wire-bar-coated nanocomposite films. Network formation in these nanocomposite films was expected to be strongly related to the electrical pathways due to inter-SWCNT bundle connections. This study suggests that the thermoelectric properties of SWCNT/P3HT nanocomposite films could be optimized by controlling their processing conditions and morphology. |
