Conjugated Polymer Nanowires: New Strategy for Enhancing Organic Thermoelectric Properties |
| 초록 |
Conjugated polymer (CP)-based organic thermoelectrics have attracted significant interest because of its low thermal conductivity, easy solution processability, non-toxicity and flexibility. To improve thermoelectric performances of organic thermoelectric generation, herein, we employed CP nanowires as a thermoelectric active layer. Through dramatically enhanced electrical conductivity obtained from doped NWs, we achieved 4.3 times improved power factor compared to doped reference film without nanostructures. Furthermore, P3HT NW-based thermoelectric devices showed excellent mechanical flexibility by maintaining 90% of its initial performance during 200 bending cycles. Based on the results, we suggest that utilization of CP NWs can be simple and very effective strategy for achieving high power generation and flexible thermoelectric applications at the same time. |
