“…The results illustrated that electrode E6 owned the highest FoM value of 8.6. The obtained value is slightly higher than the previously published values [10,13,14]. This value is even equivalent to the FoM of a commercial ITO electrode [14].…”

“…Besides, the PEDOT:PSS layer above also reduced the electrode's surface roughness. The Rq value of electrode E6 is lower than that of the electrode which coats 1072 only one GO layer or one PEDOT:PSS layer on AgNWs electrode in the previous studies [14,24]. Therefore, by using the five-layer structure PEDOT:PSS/GO/AgNW/GO/ PEDOT:PSS, the surface roughness, which was a drawback of the AgNWs electrode, was significantly improved with the low Rq value of 8 nm.…”

“…Moreover, the electrode exhibited high durability because GO could shield AgNWs from the effects of the environment [12]. In addition, there have been several reports using PEDOT:PSS to improve the roughness surface as well as the conductivity of the AgNWs electrode [13,14]. Therefore, the quality of the electrode may be improved by optimizing the structure based on AgNWs, GO, and PEDOT:PSS materials.…”

High-performance flexible multilayer transparent conducting electrodes (TCE) based on silver nanowires (AgNWs), graphene oxide (GO), and poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) materials on the flexible polyethylene terephthalate (PET) substrate were successfully fabricated by spin-coating technique. The multilayer electrodes were fabricated using different combinations of AgNWs, GO, and PEDOT:PSS materials. The morphological, physical properties, surface roughness, and durability of the fabricated electrodes were investigated. The results indicated that the five-layer structured electrode of PEDOT:PSS/GO/AgNW/GO/PEDOT:PSS possesses the best performance with a sheet resistance of 23 Ω/sq, transmittance of 85 %, and the figure of merit (FoM) value of 8.6, which is equivalent to the commercial ITO electrode. Besides, the five-layer structured electrode possessed a surface roughness of only 8 nm. The PEDOT:PSS/GO/AgNW/GO/PEDOT:PSS electrode also exhibited high durability after being exposed to the environment for 30 days. Owing to the combination of AgNWs, GO, and PEDOT: PSS materials, the five-layer electrode of PEDOT:PSS/GO/AgNW/GO/PEDOT:PSS improved the inherent disadvantages of AgNWs electrodes. In addition, the electrode possessed good conductivity, high stability, low cost, and simplicity. The electrode can be used as a promising electrode in optoelectronic devices.

Silver nanowire (AgNW) electrodes are among the most essential flexible transparent electrodes (FTEs) emerging as promising alternatives to brittle indium tin oxide (ITO) electrodes. The polymer comprising the plastic substrate to which the AgNWs are applied must also satisfy the mechanical requirements of the final device and withstand the device processing conditions. However, AgNW-based FTEs have some limitations, such as poor adhesion to coated plastic substrates, surface roughness, and difficulty in patterning. This study demonstrates a new strategy for creating AgNW-based patterned flexible poly(ethylene 2,6naphthalate) (PEN)-based electrodes with appreciable optical and electrical properties. Introducing poly(2-hydroxyethyl methacrylate) on the PEN substrate enhanced the adhesion between the substrate and AgNWs and improved the dispersibility of the AgNWs. Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) and a small amount of 2,4-hexadiyne-1,6-diol as a photosensitizer were coated onto the AgNW layer to improve the surface roughness and achieve an effective electrode pattern. By varying the AgNW concentration, we could tune the density and thickness of the AgNWs to optimize the sheet resistance and transmittance. Optimized AgNWs with a sheet resistance of 22.6 Ω/□ and transmittance of 92.3% at 550 nm were achieved. A polymer solar cell (PSC) was fabricated to evaluate the characteristics of the device employing the flexible electrodes. This PSC showed not only a high power conversion efficiency of 11.20%, similar to that of ITO-based devices, but also excellent mechanical stability, which is difficult to achieve in ITO-based flexible devices.

“…The conductors for the flexible and stretchable PCBs must exhibit outstanding electrical conductivity and mechanical deformability to prevent physical damage and communication performance variation in the bending or stretching states. Over the past decade, various flexible and stretchable conductors using metal nanoparticles and nanowires, − carbon nanotubes, ,− graphene, − and conducting polymers − have been developed as the wiring component of the integrated circuit. These conductive materials are used as electrical fillers and dispersed in elastomeric matrices, such as silicones or polyurethanes. ,,− However, such an approach commonly leads to a trade-off between electrical conductivity and mechanical deformability, limiting mechanical degrees of freedom and communication-capable frequency. ,,, Therefore, new conductive materials that exhibit high electrical conductivity, low surface roughness, and superior mechanical deformability should be developed for high-performance 5G communication PCBs.…”

With the advent of 5G wireless and Internet of Things technologies, flexible and stretchable printed circuit boards (PCBs) should be designed to address all the specifications necessary to receive signal transmissions, maintaining the signal integrity, and providing electrical connections. Here, we propose a silver nanoparticle (AgNP)/silver nanowire (AgNW) hybrid conductor and high-quality microprinting technology for fabricating flexible and stretchable PCBs in high-performance 5G wireless communication. A simple and low-cost reverse offset printing technique using a commercial adhesive hand-roller was adapted to ensure high-resolution and excellent pattern quality. The AgNP/ AgNW micropatterns were fabricated in various line widths, from 5 μm to 5 mm. They exhibited excellent pattern qualities, such as fine line spacing, clear edge definition and outstanding pattern uniformity. After annealing via intense pulsed light irradiation, they showed outstanding electrical resistivity (15.7 μΩ cm). Moreover, they could withstand stretching up to a strain of 90% with a small change in resistance. As a demonstration of their practical application, the AgNP/AgNW micropatterns were used to fabricate 5G communication antennas that exhibited excellent wireless signal processing at operating frequencies in the C-band (4−8 GHz). Finally, a wearable sensor fabricated with these AgNP/ AgNW micropatterns could successfully detected fine finger movements in real time with excellent sensitivity.
