Copper nanowires (Cu NWs) are suitable material as an electrode for flexible, stretchable and wearable devices due to their excellent mechanical properties, high transparency, good conductivity, and low cost, but oxidation problem limits their practical use and application. In order to use Cu NWs as an electrode for advanced flexible, stretchable and wearable devices attached directly to the skin, the influence of the body temperature on the oxidation of Cu NWs needs to be investigated. In this paper, the oxidation behavior of Cu NWs at high temperature (more than 80 °C) as well as body temperature is studied which has been remained largely questionable to date, and an effective encapsulation method is proposed to prevent the oxidation of Cu NWs electrode in the range of body temperatures.
铜纳米线（CuNWs）由于其优异的机械性能、高透明度、良好的导电性和低成本，是作为用于柔性、可拉伸和可穿戴设备的电极的理想材料，但氧化问题限制了它们的实际使用和应用。为了将 CuNWs 用作直接附着在皮肤上的先进柔性、可拉伸和可穿戴设备的电极，需要研究体温对 CuNWs 氧化的影响。本文研究了高温（80°C 以上）以及体温下 CuNWs 的氧化行为，这在很大程度上是目前尚未解决的问题，并提出了一种有效的封装方法，以防止 CuNWs 电极在体温范围内氧化。
