“…The main obstacle for CuNW‐based devices is the oxidation under ambient conditions that is rapidly enhanced at higher temperatures, as shown in Figure d). In order to reduce the chemical degradation of CuNW networks, various encapsulation materials such as PEDOT:PSS, electroplated Sn and poly(methyl methacrylate) (PMMA) were tested with success . This study presents the characterization of the electrical properties as well as the transient temperature and resistance response of CuNW films that are deposited onto glass substrate and subjected to Joule heating.…”

Due to the high abundance of copper on the earth and its high intrinsic electrical conductivity, copper nanowires (CuNWs) represent a promising material for transparent electrodes. In this work, an environmentally friendly and scalable synthesis that requires a low process temperature is studied. The optimum temperature is found at 79 °C, which results in nanowires with the lowest diameters. The as‐synthesized solution is sprayed to transparent conducting films, which are in turn subjected to various post‐treatments such as thermal sintering or washing with propionic acid to enhance their electro‐optical performance. Following both the optimum protocol for the synthesis and post‐treatment, a sheet resistance of 10.3 Ω ◻−1 at a transparency of 83.4% is achieved. Moreover, the CuNW‐films are tested as transparent heaters and show a homogeneous heat distribution. For the electrical properties of the films, a temperature dependence of resistance that is lowered around 28% compared to the one for bulk copper is found.

“…The flexible nature of Cu-based transparent conductors additionally makes possible the flexible or stretchable solar cells, which are highly desired in future electronics applications [159,160]. Till now, Cu-based transparent conductors have been successfully used in polymer solar cells [15,[161][162][163][164][165], perovskite solar cells [166], and semiconductor-liquid junction solar cells [167].…”

“…In order to reduce the roughness of the conductive network, PEDOT:PSS is spin-coated on top of CuNWs, and at the mean time serves as a protection layer to avoid the oxidation of Cu [164]. An alternative way is used by embedding the spray-coated CuNWs on a smooth PEDOT: PSS film [162]. Fig.…”

Soft electronics that can simultaneously offer electronic functions and the capability to be deformed into arbitrary shapes are becoming increasingly important for wearable and bio-implanted applications. The past decade has witnessed tremendous progress in this field with a myriad of achievements in the preparation of soft electronic conductors, semiconductors, and dielectrics. Among these materials, copper-based soft electronic materials have attracted considerable attention for their use in flexible or stretchable electrodes or interconnecting circuits due to their low cost and abundance with excellent optical, electrical and mechanical properties. In this review, we summarize the recent progress on these materials with the detailed discussions of the synthesis of copper nanomaterials, approaches for their assemblies, strategies to resist the ambient corrosion, and their applications in various fields including flexible electrodes, sensors, and other soft devices. We conclude our discussions with perspectives on the remaining challenges to make copper soft conductors available for more widespread applications.

“…These chemical and thermal instabilities of CuNWs are the main challenges to their use as stretchable and transparent electrodes. Thus, to solve these problems, a variety of reports have introduced stretchable and transparent electrodes with hybrid structures of CuNWs and other materials, such as carbon nanomaterials, conductive polymers, and metal-based materials [44,[47][48][49][50][51][52]. Graphene, a representative carbon nanomaterial, has high mechanical strength and thermal resistance and low water vapor and oxygen permeability [48][49][50].…”

The recent advent of unprecedented wearable applications engendered the need for stretchable electronics, which can be realized by making the individual components stretchable. The transparent conducting electrode is one of the most important components of optoelectronic devices. Therefore, developing transparent electrodes in a stretchable form is essential for the implementation of stretchable electronics. In this paper, the recent efforts in the development of stretchable and transparent electrodes, particularly those using nanomaterials such as metal nanowires, metal nanofibers, and carbon nanotubes are introduced.
