Abstract
We indicated high performance and stability transparent heaters based on AlOx covered Ag nanowires. We obtained an AlOx covered Ag nanowire thin film which has a 47 ohm/sq of sheet resistance and 88.1% (substrate included) of transmittance at 600 nm on a flexible substrate. We demonstrate that the thin AlOx layer leads to increased contact area at the junction of Ag nanowires, which contributes to lower sheet resistance and improved adhesion of Ag nanowires. Furthermore, high stability and flexibility of Ag nanowire have been achieved by the AlOx layer. Finally, we fabricated a flexible transparent heater with AlOx covered Ag nanowire, and obtained a temperature of 81 °C within 40 sec at the driven voltage of 7 V with fast response and uniform temperature distribution. Therefore, the AlOx covered Ag nanowire film is a promising candidate for the application of the flexible transparent heaters.
Highlights
Transparent heaters are commonly used in a wide range of applications such as solar panels, vehicle defrosters, periscopes, and smart, heat-retaining windows
Regardless of AlOx thickness, the sheet resistance of AlOx covered AgNWs were almost the same with 3 nm-thick AlOx covered AgNWs. These results indicate that AlOx thicknesses (3~15 nm) are not related to the sheet resistance of AgNWs
We have demonstrated the effects of the AlOx protection layer by the reactive sputtering method on the electrical, optical, and structural properties of AgNWs prepared by drop-casting and air-dry process
Summary
Transparent heaters are commonly used in a wide range of applications such as solar panels, vehicle defrosters, periscopes, and smart, heat-retaining windows. The poor adhesion of metal network to the substrate limits its wide applications[23,39], high stability against humidity and period of metal nanowires have not yet been achieved simultaneously for transparent conductive materials. Its higher temperature process over 100 °C limits a variety of flexible substrates To overcome these problems, we investigated the effect of the AlOx protection layer on Ag nanowires using physical vapor deposition (PVD) method to gain a good adhesion and stability with high transmittance and conductivity. We demonstrate the fabrication of a highly transparent, conductive, and stable AlOx covered Ag nanowires based on a flexible transparent heater, 81 °C of temperature within 40 sec at the driven voltage of 7 V has been achieved. The results show that the AlOx protection layer on Ag nanowires can significantly reduce the sheet resistance and increased stability of Ag nanowires, which can enhance heat generation behavior and duration of usage for flexible transparent heater applications
