One-Step Interface Engineering for All Inkjet-Printed All Organic Components in Transparent, Flexible Transistors and Inverters |
초록 |
A one-step interface engineering is used on both polymer electrodes and gate dielectric for all-inkjet-printed, flexible, transparent OTFTs and inverters. Dimethylchlorosilane-terminated polystyrene (PS) is introduced as a surface modifier to cured PVP dielectric and PEDOT:PSS electrodes without any pretreatment. On the benefit of the PS interlayer, the electrical properties of the TIPS-pentacene based OTFTs on a flexible plastic substrate are significantly improved, as shown by a field-effect mobility of 0.27 cm2V-1s-1. In contrast, the untreated system shows a low mobility of less than 0.02 cm2V-1s-1. Additionally, the all-inkjet-printed PS-treated inverters exhibit a voltage gain of 7.17 VV-1. The TFTs and inverters, including deformable and transparent PEDOT:PSS electrodes, exhibit a light transmittance of higher than 70%. Specifically, there is no significant degradation in the electrical performance of the interface engineered system after 1000 bending cycles at a radius of 5 mm. |
