“…First, research works have been devoted to exploring the solvent possibilities of organic semiconductors, allowing the modulation of the semiconductor morphology and charge transport [45][46][47]. For instance, Kim et al investigated the effect of different solvents on the thin film morphology and crystallinity of TIPS pentacene [48].…”

“…Thus, it could produce high-quality TIPS-pentacene thin film with large grain size and more convergent crystalline microstructure. Furthermore, high-quality inkjet-printed TIPS-pentacene thin film and accordingly high-performance TFTs could be achieved via modifying the dielectric surface properties, in which inserting SAM, e.g., phenethyltrichlorosilane (PETS), phenyltrichlorosilane (PTS) and perfluorodecyltrichlorosilane (PDTS). , In addition, UV-ozone treatment on substrate could also control the morphology, crystallization behavior and device performance of TIPS-pentacene via inkjet printing. The UV irradiation accelerates the formation of uniform and large strip-like crystals (Figure c), leading to the mobility of TIPS-pentacene TFTs fabricated via inkjet printing up to 0.48 cm 2 V –1 s –1 .…”

Thin-film transistors (TFTs) have experienced tremendous development during the past decades and show great promising applications in flat displays, sensors, radio frequency identification tags, logic circuit, and so on. The printed TFTs are the key components for rapid development and commercialization of printed electronics. The researchers in China play important roles to accelerate the development and commercialization of printed TFTs. In this review, we comprehensively summarize the research progress of printed TFTs on rigid and flexible substrates from China. The review will focus on printing techniques of TFTs, printed TFT components including semiconductors, dielectrics and electrodes, as well as fully printed TFTs and printed flexible TFTs. Furthermore, perspectives on the remaining challenges and future developments are proposed.

“…When the droplet has a pinned three phase contact line (TCL), the excess solvent lost at the edge is replenished by the solvent in the centre, leading to a radial capillary flow. The capillary flow carries the solutes in evaporating droplet towards the pinned TCL, thus the ring-like morphology is formed (Sun et al, 2015;Eales et al, 2016;Wang et al, 2015;Pillai et al, 2016).…”

Purpose This paper aims to find the optimal deposition conditions for achieving the homogenous structure of the silver layers onto three types of polymeric substrates as well as on the rigid substrates. For this reason, the detailed investigation of the silver-based layers deposited at different technological conditions by microscopic methods is presented in this paper. Design/methodology/approach The special test pattern has been designed and deposited at different substrate temperatures by using two types of generally available silver-based nano-inks. Cross-sections and 3D profiles of the deposited silver layers have been profoundly analysed by using the optical profiler Sensofar S Neox on the generally used polymeric (PI, PET and PEN) and rigid substrates (951 and 9K7 LTCC, glass and alumina). Findings The results prove the strong correlation between the substrate temperature during the deposition process and the final shape of the created structure which has the a direct impact on the layers’ homogeneity. The results also prove the theory of the coffee ring effect creation in the inkjet printing technology. Originality/value The main benefit of this paper lies in the possibility of the homogeneity achievement of the deposited silver-based layers on the several polymeric and rigid substrates by managing the temperature during the deposition. The paper also offers the comparative study of nano-inks’ behaviour on several polymeric and rigid substrates.
