Enhanced solvent resistance and electrical performance of electrohydrodynamic printed PEDOT:PSS composite patterns: Effects of hardeners on the performance of organic thin-film transistors |
| 초록 |
Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) are of great interest as promising metal-free electrodes for future electronic devices. Several printing techniques have been consequently developed to obtain the PEDOT:PSS patterns. In this study, we introduced a silicon-based hardener in PEDOT:PSS composites to prepare conductive ink for the purpose of realizing solvent-resistive PEDOT:PSS composite patterns. Electrohydrodynamic (EHD) printing enabled the direct patterning of the PEDOT:PSS and hardener composites that exhibited improvement in electrical conductivity and solvent resistance, which is advantageous for efficient charge injection when semiconductor materials are coated on the pre-deposited PEDOT:PSS composite electrodes. |
