“…Similar to double‐shot inkjet printing, Zhao and coworkers proposed a dual‐droplet inkjet printing process to deposit monolayer NP films . As shown in Figure f, the first water droplet (supporting droplet) acting as the Langmuir–Blodgett trough and the second droplet containing polystyrene (PS) NPs (wetting droplet) were inkjet printed at the same position by two nozzles.…”

PE has been explored for the manufacturing of flexible and stretchable electronic devices by printing functional inks containing soluble or dispersed materials, [14][15][16] which has enabled a wide variety of applications, such as transparent conductive films (TCFs), flexible energy harvesting and storage, thin film transistors (TFTs), electroluminescent devices, and wearable sensors. [17][18][19][20][21][22][23][24] The global PE market should reach $26.6 billion by 2022 from $14.0 billion in 2017 at a compound annual growth rate of 13.6%. [25] PE devices are manufactured by a variety of printing technologies. Typical printing technologies can be divided into two broad categories: noncontact patterning (or nozzle-based patterning) and contact-based patterning. The noncontact techniques include inkjet printing, electrohydrodynamic (EHD) printing, aerosol jet printing, and slot die coating, while screen printing, gravure printing, and flexographic printing are examples of the contact techniques. Each of these techniques has its own advantages and disadvantages, but they all rely on the principle of transferring inks to a substrate. Understanding the characteristics and recent advances of each printing technique is important to further the progress in PE. Moreover, to promote the lab-scale printing technologies to large-scale production process, roll-toroll (R2R) printing, which is one of the manufacturing methods to obtain large-area films with low cost and excellent durability, has drawn much attention from both industry and the research community.Nearly all of devices based on PE require conductive structures, interconnects, and contacts; therefore, highly conductive patterns, usually with high transparency and/or high resolution, fabricated by means of printing conductive materials are one of the most critical components in PE devices. Various printable conductive nanomaterials, such as metal nanomaterials (e.g., metal nanoparticles and metal nanowires) and carbon nanomaterials (e.g., graphene and carbon nanotubes (CNTs)), have been explored and used as major materials for PE. Applying printing technology to deposition of the conductive nanomaterials requires formulation of suitable inks. After depositing inks on different substrates, post-printing treatment, Printed electronics is attracting a great deal of attention in both research and commercialization as it enables fabrication of large-scale, low-cost electronic devices on a variety of substrates. Printed electronics plays a critical role infacilitating widespread flexible electronics and more recently stretchable electronics. Conductive nanomaterials, such as metal nanoparticles and nanowires, carbon nanotubes, and graphene, are promising building blocks for printed electronics. Nanomaterial-based printing technologies, formulation of printable inks, post-printing treatment, and integration of functional devices have progressed substantially in the recent years. This review summarizes basic principles and recent development of common printing technologie...

“…It has been demonstrated that the nature of the functional groups and the electrostatic interactions between nanoparticles affect the spreading of the wetting droplet and the morphology of the deposited film. The deposition of carboxyl‐PS particles strongly depends on the pH of the supporting droplet and changes from coffee ring patterns at high pH to nearly uniform monolayers at low pH [128] . At pH >7, the zeta potential (absolute value) of the carboxyl‐PS particles increases, leading to high particle–particle electrostatic repulsion.…”

Driven by the development of new functional inks, inkjet-printed electronics has achieved several milestones upon moving from the integration of simple electronic elements (e.g., temperature and pressure sensors, RFID antennas, etc.) to high-tech applications (e.g. in optoelectronics, energy storage and harvesting, medical diagnosis). Currently, inkjet printing techniques are limited by spatial resolution higher than several micrometers, which sets a redhibitorythreshold for miniaturization and for many applications that require the controlled organization of constituents at the nanometer scale. In this Review, we present the physico-chemical concepts and the equipment constraints underpinning the resolution limit of inkjet printing and describe the contributions from molecular, supramolecular, and nanomaterials-based approaches for their circumvention. Based on these considerations, we propose future trajectories for improving inkjet-printing resolution that will be driven and supported by breakthroughs coming from chemistry. Please check all text carefully as extensive language polishing was necessary. Title ok? Yes

“…Al-Milaji et al employed a dual-droplet inkjet printing configuration to transpose the Langmuir-Blodgett (LB) technique to the picoliter droplets ejected from an inkjet printer. [126][127][128] Monolayers of closely packed nanoparticles were obtained by consecutive dual-droplet printing of a supporting droplet and a wetting droplet containing polystyrene (PS) nanoparticles. When the colloidal suspension spread over the surface of the supporting droplet, nanoparticles self-assembled at the interface between the wetting droplet and the supporting droplet.…”
