“…This electrode eliminates the contact resistance between NFs, resulting in a low sheet resistance of 0.2 Ω sq −1 with a transmittance of 90%. Furthermore, the W mesh has excellent anti-corrosion and anti-thermal properties [194]. By matching the rotating speed of the receiver and the discharge speed of the feeding device, the patterned electrode can be prepared simply and efficiently.…”

Flexible and stretchable transparent electrodes are widely used in smart display, energy, wearable devices and other fields. Due to the limitations of flexibility and stretchability of indium tin oxide (ITO) electrodes, alternative electrodes have appeared, such as metal films, metal nanowires, and conductive meshes. However, few of the above electrodes can simultaneously have excellent flexibility, stretchability, and optoelectronic properties. Nanofiber (NF), a continuous ultra-long one-dimensional conductive material, is one of the most promising materials for high-performance transparent electrodes with excellent properties due to its unique structure. This paper summarizes the important research progress of NF flexible transparent electrodes (FTEs) in recent years from the aspects of NF electrode materials, preparation technology and application. First, the unique advantages and limitations of various NF materials are systematically discussed. Then, we summarized the preparation technology of various advanced NF FTEs, and pointed out the future development trend. We also discussed the application of NFs in solar cells, supercapacitors, electric heating equipment, sensors, etc., and analyzed its development potential in flexible electronic equipment, as well as problems that need to be solved. Finally, the challenges and future development trends are proposed for the wide application of NF FTEs in the field of flexible optoelectronics.

Although graphene films are the main candidate for replacing scarce and brittle metal‐oxide transparent conductors, the current challenges on graphene deposition and patterning are severely limiting their commercial application. Here, materials and methods that allow large‐scale, efficient, and low‐cost fabrication of highly transparent conductors in a few minutes are demonstrated. First, a low‐cost graphene oxide (GO) solution through spray coating is deposited, followed by simultaneous reduced graphene oxide reduction and thinning through a low‐cost nanosecond fiber laser. It is shown that a 1064 nm master oscillator power amplifier laser enhances the conductivity of GO coated sample by ≈60 times, with excellent optical transparency of 90%. The laser parameters are adjusted, and creation of various shades of transparency, conductivity, and a full ablation are demonstrated. This way, complex GO‐based circuits can be produced rapidly. Compared to the existing techniques that require chemical vapor deposition, and chemical/thermal reduction, this technique is considerably more accessible, replicable, and can open doors for various applications in optoelectronics, energy storage/harvesting, and sensing. The electrical, chemical, and optical properties of the samples are characterized before and after laser treatment, through optical profilometry, scanning electron microscopy, and (UV, Raman, and energy dispersive X‐ray) spectroscopy and applications in transparent conductors, and laser‐patterned high‐resolution and miniaturized interdigitated sensors are shown.

Commercial indium tin oxide (ITO) has been limited in utility due to its brittleness and high cost. Here, a flexible Sn-Cu hybrid metallic network with a low sheet resistance of 3.71 X sq À1 at 90% transparency was synthesized by a facile solution electro-writing method, exceeding the performance of ITO film. By incorporating Sn nanoparticles into a Cu microfiber network matrix, a heating-induced self-healing recoverable metallic network was obtained. The Sn-Cu microfiber transparent conductive electrode (TCE) endured a sheet resistance increase of $ 2.6% after 1000 bending cycles, and a decrease of $ 2.0% was found after a heating-induced self-healing process was subsequently conducted on the TCE. These results indicate that the proposed Sn nanoparticle incorporated self-healing copper metallic network can be expected to be a potential replacement for conventional ITO film and could be widely used in flexible and recoverable electronics.
