“…In addition to the potential technological integration issues that have been previously listed, device optimization should also require tuning the work function of the electrodes [170] to ease charge carrier injection or collection in optoelectronic devices with any active layers. For this purpose, transparent flexible electrodes can for instance be modified by coating with another transparent layer (organic compounds, metallic oxides.…”

“…Not only the properties of the active layer itself, but also the interfaces with their neighbouring layers and the electrodes are of overwhelming importance [179]. A few studies have examined metallic nanowire-based OLEDs: good electroluminescent properties have been reported [97,133,170,180]. In particular, Yu et al have integrated AgNW polymer composite electrodes in large angle bending PLEDs (see figure 10).…”

“…As in OPV devices, a slight increase of device performance through higher power efficiency of AgNW-based OLED devices compared to conventional ITO has been observed [27,97,170,[181][182][183]. This is partly ascribed to an enhanced scattering of emitted light by AgNWs.…”

The class of materials combining high electrical or thermal conductivity, optical transparency and flexibility is crucial for the development of many future electronic and optoelectronic devices. Silver nanowire networks show very promising results and represent a viable alternative to the commonly used, scarce and brittle indium tin oxide. The science and technology research of such networks aims at better understanding the physical and chemical properties of this nanowire-based material while opening attractive new applications.

“…The sputtering deposition of ITO (the most common method for ITO deposition) on flexible substrates results in a thin film with high sheet resistance due to the low-temperature thermal treatment that is required by the substrate. Furthermore, low mechanical resistance and cost of producing ITO limit its application as a transparent electrode for OLEDs [86]. Metal NWs show great potential to be used as transparent conductive electrodes (as both anode and cathode) for OLEDs.…”

With ever-increasing demand for lightweight, small, and portable devices, the rate of production of electronic and optoelectronic devices is constantly increasing, and alternatives to the current heavy, voluminous, fragile, conductive and transparent materials will inevitably be needed in the future. Conductive metal nanomaterials (such as silver, gold, copper, zinc oxide, aluminum, and tin) and carbon-based conductive materials (carbon nanotubes and graphene) exhibit great promise as alternatives to conventional conductive materials. Successfully incorporating conductive nanomaterials into thin films would combine their excellent electrical and optical properties with versatile mechanical characteristics superior to those of conventional conductive materials. In this review, the different conductive metal nanomaterials are introduced, and the challenges facing methods of thin film deposition and applications of thin films as conductive coatings are investigated.

Stretchable electroluminescent (EL) devices are a new form of mechanically deformable electronics that are gaining increasing interests and believed to be one of the essential technologies for next generation lighting and display applications. Apart from the simple bending capability in flexible EL devices, the stretchable EL devices are required to withstand larger mechanical deformations and accommodate stretching strain beyond 10%. The excellent mechanical conformability in these devices enables their applications in rigorous mechanical conditions such as flexing, twisting, stretching, and folding.The stretchable EL devices can be conformably wrapped onto arbitrary curvilinear surface and respond seamlessly to the external or internal forces, leading to unprecedented applications that cannot be addressed with conventional technologies. For example, they are in demand for wide applications in biomedical-related devices or sensors and soft interactive display systems, including activating devices for photosensitive drug, imaging apparatus for internal tissues, electronic skins, interactive input and output devices, robotics, and volumetric displays. With increasingly stringent demand on the mechanical requirements, the fabrication of stretchable EL device is encountering many challenges that are difficult to resolve. In this review, recent progresses in the stretchable EL devices are covered with a focus on the approaches that are adopted to tackle materials and process challenges in stretchable EL devices and delineate the strategies in stretchable electronics. We first introduce the emission mechanisms that have been successfully demonstrated on stretchable EL devices. Limitations and advantages of the different mechanisms for stretchable EL devices are also discussed. Representative reports are reviewed based on different structural and material strategies. Unprecedented applications that have been enabled by the stretchable EL devices are reviewed. Finally, we summarize with our perspectives on the approaches for the stretchable EL devices and our proposals on the future development in these devices.
