Structure-Property Relationships of Semiconducting Polymers for Flexible and Durable Polymer Field-Effect Transistors |
| 초록 |
We report high-performance top-gate bottom-contact flexible field-effect polymer transistors (FETs) fabricated by flow-coating diketopyrrolopyrrole based and naphthalene diimide based polymers as semiconducting channel materials. All of the polymers displayed good FET characteristics with on/off current ratios exceeding 107. The highest hole mobility of 1.51 cm2V-1s-1 and the electron mobility of 0.85 cm2V-1s-1 were obtained from the P(DPP2DT-T2) and P(NDI2OD-Se2) polymer FETs, respectively. The impacts of the polymer structures on the FET performance are well explained by the crystallinity, the tendency of the polymer backbone to adopt an edge-on orientation, and the interconnectivity of polymer fibrils in the film state. Additionally, we demonstrated that all of the polymer-based flexible FETs were highly resistant to tensile stress, with negligible changes in their characteristics during a bending test. |
