Silver nanowires (AgNWs) have received much attention from researchers for their superior optoelectronic properties and are thought to be the most potential substitute for indium−tin oxide. However, the poor stability of the AgNW network when exposed to the atmospheric environment for a long time is a pivotal problem. The surface of the AgNW is easily oxidized, and the NW scale is too small, accelerating the degradation mechanism of Ag, which is limited in practical applications. In this study, a simple and inexpensive solution approach is innovatively proposed to prepare ultrathin Ag@ZnO NW networks with core−shell structure to improve the thermal, electrical, and chemical stability of AgNWs. The formed Ag@ZnO NW network has a high transmission of 81% with a low sheet resistance of 7.5 Ω/sq. More importantly, the Ag@ZnO NW network can withstand high temperatures up to 280 °C without performance degradation. In addition, the Ag@ZnO NW network shows excellent thermal and chemical stability and maintains the original performance under harsh conditions such as high temperature, high relative humidity, ultraviolet ozone, strong oxidants (Na 2 S), and salinity (NaCl). Finally, the application of Ag@ZnO NW flexible transparent conductive electrodes (FTCEs) in an electrochromic device is successfully demonstrated to verify the applicability of Ag@ZnO NW FTCEs, and the electrochromic device has cyclability and quick responsiveness.

“…Larger-aspect-ratio NWs allow a fewer number of junctions, leading to the lower overall junction resistance at the same optical transmittance for the nanowire conductive networks. 59 Therefore, Ag NWs with average diameters of ∼60 nm and aspect ratios of ∼1700 are used to fabricate the NiO@Ag NW-based FTHs. First of all, a small amount of a NiF 2 water solution is dropped into an alcohol suspension of Ag NWs.…”

High-performance electrical heaters with high transmittance, fast response speed, superior heat resistance, ultraflexibility, high working temperature, and sufficient stabilities are highly desirable for application in heating systems in areas such as healthcare and aerospace. Herein, we demonstrate an ultrahigh-temperature-tolerant flexible transparent heater (FTH) consisting of a NiO@Ag core–shell nanowire (NiO@Ag NW) network and a colorless polyimide (cPI) film. NiO nanoshells are formed uniformly on the surface of Ag NWs through the solution process, which enhances the stability of Ag NWs. The heating behaviors and transmittance can be controlled by the NiO@Ag NW spin-coating cycle. The NiO@Ag NW-based FTHs show a fast thermal response of ∼15 s, a high transmittance of 86.2% in the visible region, and a large thermal figure of merit of 30.7 m2·°C/W under optimal preparation conditions. The saturation temperature of FTHs has barely changed after 20 taping tests and 1000 bending cycles at a bending radius of 0.5 mm. Particularly, the heating temperature of FTHs can reach 266 °C in the air under an applied voltage of 9 V. Moreover, the FTHs possess sufficient heating reliability, stability, and repeatability during the long-term and repeated heating cycles. In addition, the FTHs are resistant to a number of harsh environments.
