报告摘要:
Printing technology has been developed more than 2000 years and the related products play a critical role in our daily life and civilization. The printed electronics only developed for several decades and still in its infant stage. Compared with the printed organic electronics, more and more research is focusing on inorganic electronics due to its more stable performance, cheaper raw materials, less fabrication process and lower cost assembling. In this work, we summarize our research on the printed electronic devices with inorganic materials, including thin film transistors (TFTs), supercapacitor and lithium ion batteries (LIBs). For example, we employed ink-jet printing technology to fabricate In-Ga-Zn oxide TFTs with a high mobility of 1.41 cm2/V s and on/off ratio of 4.3e7. As for the energy storage devices, screen printing technology was introduced to fabricate solid-state flexible microsupercapacitors for the first time. It is worth mentioning that the developed technology is a general route to print various active materials into microsupercapacitors onto different substrates, including glass, PET plastic film and even printing paper. We have integrated CNT, onion-like carbon (OLC), MnO2/OLC, CoO/CNT etc. into the flexible microsupercapacitors by screen printing technology and the devices exhibit excellent electrochemical performance even under bended status. We also developed flexible LIBs with sandwich structure with 3D printing technology. The detailed mechanism and working principle is still under investigation.
