银纳米线(AgNW)网络是取代ITO薄膜的最有前途的候选材料之一，在许多不同的应用领域。近年来，Ag-NW系透明加热器(THs)表现出优异的加热性能。为了克服Ag NW网络的不稳定性问题，研究人员提出了不同的混杂结构。然而，这些方法不仅需要额外的处理，而且还会降低Ag NW网络的光学性能。因此，研究和确定Bare-Ag-NW网络THs的热性能极限具有重要意义。在这里，我们报道了NW密度、接触几何、外加偏压、弯曲和增量偏压对Ag NW网络TH性能的影响。基于Ag-NW网络的TH的方阻和透过率分别为4.3Omega sq(-1)和83.3%，NW密度为1.6 NWµm(-2)，在递增偏压下(最大5V)，最高温度达到275℃。通过这一性能，我们的结果为基于裸-银-NW网络的透明加热器提供了一个不同的视角。
Silver nanowire (Ag NW) networks are one of the most promising candidates for the replacement of indium tin oxide (ITO) thin films in many different applications. Recently, Ag-NW-based transparent heaters (THs) showed excellent heating performance. In order to overcome the instability issues of Ag NW networks, researchers have offered different hybrid structures. However, these approaches not only require extra processing, but also decrease the optical performance of Ag NW networks. So, it is important to investigate and determine the thermal performance limits of bare-Ag-NW-network-based THs. Herein, we report on the effect of NW density, contact geometry, applied bias, flexing and incremental bias application on the TH performance of Ag NW networks. Ag-NW-network-based THs with a sheet resistance and percentage transmittance of 4.3 Omega sq(-1) and 83.3%, respectively, and a NW density of 1.6 NW mu m(-2) reached a maximum temperature of 275 degrees C under incremental bias application (5 V maximum). With this performance, our results provide a different perspective on bare-Ag-NW-network-based transparent heaters.
