“…Huang et al [17] used the capillary force and negative chemical potential at the AgNWs junctions to induce the selective epitaxial growth of AgNWs at the nanowire junctions instead of its surface, which improved the stability and conductivity without reducing the transmittance, as shown in Figure 8b. Yang et al [88] studied the sintering process of flash lamps. Under the optimal sintering process conditions, the resistance of AgNWs networks was reduced by about 20%.…”

Nowadays, flexible transparent conductive film (FTCF) is one of the important components of many flexible electronic devices. Due to comprehensive performances on optoelectronics, FTCF based on silver nanowires (AgNWs) networks have received great attention and are expected to be a new generation of transparent conductive film materials. Due to its simple process, printed electronic technology is now an important technology for the rapid production of low-cost and high-quality flexible electronic devices. AgNWs-based FTCF fabricated by using printed electronic technology is considered to be the most promising process. Here, the preparation and performance of AgNW ink are introduced. The current printing technologies are described, including gravure printing, screen printing and inkjet printing. In addition, the latest methods to improve the conductivity, adhesion, and stability of AgNWs-based FTCF are introduced. Finally, the applications of AgNWs-based FTCF in solar cells, transparent film heaters, optoelectronic devices, touch panel, and sensors are introduced in detail. Therefore, combining various printing technologies with AgNWs ink may provide more opportunities for the development of flexible electronic devices in the future.

“…[ 14,15 ] Increasing the density of Ag NWs to increase the contact area can increase the bending durability; however, this approach significantly degrades the optical properties. To solve this problem, attempts have been made to enhance bending durability by improving the network of NWs through physical [ 15–21 ] or chemical bonding. [ 22–24 ] Choi et al [ 15 ] fabricated sintered Ag NWs with enhanced networking by bonding NWs using roll‐to‐roll wet sinter forging.…”

As the demand for foldable or rollable smart electronic devices increases, the issue of damage caused by cyclic fatigue of the flexible transparent electrode (FTE) due to repeated bending stress at extremely low bending radius is emerging. Herein, it is demonstrated that a mesh electrode composed of silver nanowires (Ag NW–mesh) with multifunctional optoelectronic performance microfabricated without photomasking via selective laser nanowelding (SLNW) followed by soft‐etching of highly ductile Ag NWs on a flexible polymer film exhibits long‐term cycling stability at bending stresses of a 1 mm radius of curvature (ROC). In the optimal NW microgrid pattern design, the cycle fatigue resistance of NW–mesh electrodes considerably increases with increase in NW areal mass density (AMD) and decreasing microgrid spacing due to the improved weldability and networkability of NWs at a low laser energy density of 1 J cm−2. A diagonally gridded NW–mesh electrode with 30 μm line spacing exhibits extremely high reliability with little change in the performance of Joule heating and electromagnetic interference shielding under long‐term bending stresses of 300 000 cycles at 1 mm ROC. Being a simple process without photomasking, this method can easily use a multifunctional FTE with ultrahigh fatigue resistance and reliability suitable for highly flexible smart devices.

In this work, the optoelectrical, mechanical, and material properties of silver nanowires/poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (AgNWs‐PEDOT:PSS) hybrid electrode, solution processed on 5 µm parylene‐C substrate for ultraflexible organic photodetector (OPD) applications, are investigated. The fabricated transparent conductive hybrid electrode exhibits low sheet resistance (Rs) of 27 Ω Sq.−1 and shows an average optical transmission of 90% in the visible spectrum. Besides the comparable work function (WF) of 5 eV when compared with the standard indium tin oxide (ITO) electrode, the surface root mean square (RMS) roughness of the hybrid electrode is effectively reduced from 8 nm to 4 nm by spin coating a planarization layer of PEDOT:PSS. With a stable value in the relative change in resistance over continuous 50 k bending cycles at a curvature radius of 0.1 mm, the hybrid electrode exhibits excellent mechanical characteristics. Finally, using this hybrid electrode it is shown that an ultraflexible OPD fabricated in ambient atmospheric conditions demonstrates current density to voltage (J–V) characteristics comparable with standard ITO‐based OPD. Further, the ultraflexible OPD can withstand more than 5 k continuous bending cycles with similar J–V characteristics before and after bending.
