“…Since the ZnO material has been widely reported for electron injection/transport layer [17], photo-transistor [18,19], nanogenerator [20], sensor [21] and composite electrodes [3], the discovery of better stability provides a new method for potential application in transparent electrodes or circuits with higher current. However, considering that heat dissipation affects resistance in printed silver nanoparticles [22], it is necessary to study whether the high thermal conductivity of oxides such as ZnO [23] plays a key role in Joule heating uniformity and AgNW stability. In this letter, solution-processed ZnO was used to fabricate nanocomposites with a gravure printed AgNW random network.…”

The electrical breakdown is a bottleneck preventing AgNW networks from being used in high-current electronics such as transparent heaters or similar applications. The process of failure confirms that Joule-heating plays a key role in the formation of cracks perpendicular to the voltage direction. To improve the transfer of Joule heating, solution-processed ZnO nanoparticles were deposited on a gravure printed AgNW random network with good transparency. The AgNW-ZnO nanocomposites show better heating uniformity at higher temperatures because of their improved thermal conductivity. A 57.7% higher power density was obtained without failure, as well as the improved maximum average temperature rise from 72.2 °C to 97.9 °C, after the AgNW was composited with ZnO. This work opens up a new method to study AgNW failures for applications in high-current electronics.
