我们展示了一个新的概念，用于制造柔性透明薄膜加热器的基础上银纳米线。由于金属纳米线的无规网络的固有性质，可以在低电压（通常低于12 V）下将联合收割机的可弯曲性、透明性和高热性能结合起来，这对于许多应用是有意义的。这在目前的透明导电氧化物技术中是不可能实现的，并且它与用碳纳米管或石墨烯制造的类似设备相比很好。我们在具有优异加热性能的玻璃和聚萘二甲酸乙二醇酯（PEN）基板（厚度为125 μ m，极薄1.3 μ m）上进行了实验。我们指出，实现透明加热器所需的银的量是非常低的，我们还提出了初步的结果表明，这种材料可以有效地用于制造光致变色显示器。据我们所知，这是第一次报告的金属陶瓷基透明薄膜加热器。我们认为，这些结果可能是一个有用的方法，为工程的高度灵活和透明的加热器，这是无法实现的现有工艺。
We demonstrate a new concept for the fabrication of flexible transparent thin film heaters based on silver nanowires. Thanks to the intrinsic properties of random networks of metallic nanowires, it is possible to combine bendability, transparency and high heating performances at low voltage, typically below 12 V which is of interest for many applications. This is currently not possible with transparent conductive oxide technologies, and it compares well with similar devices fabricated with carbon nanotubes or graphene. We present experiments on glass and poly(ethylene naphthalate) (PEN) substrates (with thicknesses of 125 mu m and extremely thin 1.3 mu m) with excellent heating performances. We point out that the amount of silver necessary to realize the transparent heaters is very low and we also present preliminary results showing that this material can be efficiently used to fabricate photochromic displays. To our knowledge, this is the first report of metallic nanowire-based transparent thin film heaters. We think these results could be a useful approach for the engineering of highly flexible and transparent heaters which are not attainable by existing processes.
