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.
我们展示了基于氧化铝覆盖银纳米线的高性能且稳定的透明加热器。我们在柔性衬底上获得了一种氧化铝覆盖的银纳米线薄膜，其在600纳米处的方阻为47欧姆/平方，透过率（包括衬底）为88.1%。我们证明，薄的氧化铝层会导致银纳米线结处的接触面积增加，这有助于降低方阻并改善银纳米线的附着力。此外，氧化铝层实现了银纳米线的高稳定性和柔韧性。最后，我们制造了一种带有氧化铝覆盖银纳米线的柔性透明加热器，在7伏驱动电压下40秒内达到了81摄氏度的温度，响应迅速且温度分布均匀。因此，氧化铝覆盖的银纳米线薄膜是柔性透明加热器应用的一个有前途的候选材料。
