Transparent and flexible electrodes are widely used on a variety of substrates such as plastics and glass. Yet, to date, transparent electrodes on a textile substrate have not been explored. The exceptional electrical, mechanical and optical properties of monolayer graphene make it highly attractive as a transparent electrode for applications in wearable electronics. Here, we report the transfer of monolayer graphene, grown by chemical vapor deposition on copper foil, to fibers commonly used by the textile industry. The graphene-coated fibers have a sheet resistance as low as ~1 kΩ per square, an equivalent value to the one obtained by the same transfer process onto a Si substrate, with a reduction of only 2.3 per cent in optical transparency while keeping high stability under mechanical stress. With this approach, we successfully achieved the first example of a textile electrode, flexible and truly embedded in a yarn.
透明且可弯曲的电极被广泛应用于各种基材上，如塑料和玻璃。然而，迄今为止，尚未有人探索过在纺织基材上制备透明电极。单层石墨烯卓越的电学、机械和光学性能使其作为可穿戴电子产品中的透明电极极具吸引力。在此，我们报告了通过化学气相沉积法在铜箔上生长的单层石墨烯转移到纺织工业常用纤维上的过程。涂覆有石墨烯的纤维的方阻低至约每平方1千欧，这一数值与通过相同转移工艺在硅基板上获得的数值相当，在保持机械应力下高稳定性的同时，光学透明度仅降低了2.3%。通过这种方法，我们成功实现了首个柔性且真正嵌入纱线中的纺织电极实例。
