“…All these drawbacks always limit their applications. One solution of these problems is to prepare composite materials of AgNWs with graphene . For example, graphene has been selected to work as the protection layer in a AgNW/graphene hybrid TCF, so that the stability of AgNWs/graphene hybrid TCE has been improved significantly thanks to protection of graphene .…”

The rising demands of optoelectronic devices, such as flexibility, stretchability, and energy efficiency, urgently require alternative transparent conductive films (TCFs) for indium tin oxide. Among all the candidates such as carbon nanomaterials, metal nanomaterials, conductive polymers, and other nanocomposites, graphene is highly promising because of its distinct properties, such as outstanding conductivity, impressive optical transparency, remarkable mechanical flexibility, and chemical/thermal stability. However, the practical application of graphene‐based TCFs (G‐TCFs) is still challenging due to the difficulty for preparing large‐area crystalline graphene with few defects for TCFs. Many efforts have been made to solve these problems, and several kinds of optoelectronic devices have been successfully fabricated with G‐TCFs. This review presents the recent development in this area made by the authors and others, including the material systems and synthetic strategies of G‐TCFs, as well as their applications as transparent electrodes in optoelectronic devices such as field effect transistors, organic light‐emitting diodes, organic solar cells, and other devices. The current major challenges in this area and the potential practical solutions are identified.

“…Homogeneous and continuous thin layers (such as TCOs, conductive polymers or some nanocomposites) are uniform by nature, while networks of carbon nanotubes or metallic nanowires, tiled graphene‐based sheets or metallic grids can appear nonhomogeneous, as demonstrated by the appearance of hot spots in the worst case. [ 190 ] The use of nanocomposites combining both continuous and discontinuous THs can prevent this nonuniformity. Haacke's FoM was used (Tr 10 / R sh ): generally speaking, apart from graphene and CNT networks this FoM has rather high values for all TH technologies.…”

Transparent heaters (TH) have attracted intense attention from both scientific and industrial sectors due to the key role they play in many technologies, including smart windows, deicers, defoggers, displays, actuators, and sensors. While transparent conductive oxides have dominated the field for the past five decades, a new generation of THs based on nanomaterials has led to new paradigms in terms of applications and prospects in the past years. Here, the most recent developments and strategies to improve the properties, stability, and integration of these new THs are reviewed.

“…In particular, Ag nanowires (AgNWs) have been extensively studied due to the ease of fabrication and integration in various devices, such as defogging windows [19][20][21][22][23][24] and heaters for sensors [25], optical modulation of liquid crystal [26], thermo chromic applications [27,28], high temperature reactors [29] and thermotherapy [30]. For practical application of AgNW film heaters, especially in humid air, the stability issues must be tackled [20,[31][32][33][34][35][36] and various means have been developed [37][38][39][40][41]. After achieving satisfactory stability, the electrothermal parameters could be systematically tuned owing to the percolation conducting structure of AgNW films for different application needs, such as a quick response, low driving voltage or low power consumption [19,42].…”

Recently, many studies have been carried out to solve the particulate matter pollution problem. However, the detection accuracy for particulate matter in the atmosphere remains unsatisfactory due to the influence of the air relative humidity. Herein, we report a Ag nanowire film air heater to enhance the detection accuracy through internal heating. From air temperature and air relative humidity relationship analysis, it has been found that the Ag nanowire film air heater can form the most suitable air relative humidity in the detection system, thereby enhancing the detection accuracy. Consequently, the Ag nanowire film air heater-assisted light scattering particulate matter detector has achieved tremendous enhancement in its detection accuracy, which is comparable with the data obtained by the beta gauge method. Film resistance plays a key role in internal air temperature distribution and the resultant air relative humidity at given voltages. To achieve the most suitable air relative humidity for continuous online monitoring, response time and power consumption should be balanced. Therefore, guidance for designing Ag nanowire films with proper resistance used in an optional-sized detector has been given for quick response, high accuracy and low power consumption. This work is of significance for providing insight for future studies in particulate matter detection and pollution remediation.
