Abstract:

In the past decades, owing to their intrinsic advantages of excellent flexibility, solution-processability, tunable physical and chemical properties, and extensive substrate applicability, organic thin-film transistors (OTFTs) have exhibited greater potential than conventional silicon-based thin-film transistors in the modern electronic industries including flexible displays and conformal sensor arrays. OTFTs can highly integrate with various printing techniques by virtue of their solution-processable characteristic, especially for printing the active layer of OTFTs channel. Starting from the fully printed OTFTs, this review discusses and summarizes various printing strategies for transistor fabrication, including screen printing, slot-die printing, gravure printing, inkjet printing, and other printing techniques. Furthermore, printing-compatible ink materials for different components of transistor are summarized, including the metal nanoparticle ink for printing metallic electrodes, the crosslinkable polymer ink for printing dielectric layer, and the carbon-based, conjugated small molecule-based, conjugated polymer-based ink for printing channel layer. In addition, considering the working mode of transistors, this review further discusses the transistor types available of fully printing fabrication, such as organic field effect transistors, electrolyte�瞘ating organic field effect transistors, and organic electrochemical transistors. Finally, the challenges and future research direction on the fully printing of OTFTs and more complex circuits are outlooked.
