The traditional Ag nanowire preparation means that it cannot meet the demanding requirements of photoelectrochemical devices due to the undesirable conductivity, difficulty in compounding, and poor heat resistance. Here, we prepared an Ag nanonetwork with superior properties using a special template method based on electrospinning technology. The transparent conductive films based on Ag nanonetworks have good transmittance in a wide range from ultraviolet to visible. It is important that the films have high operability and are easy to be compounded with other materials. After compounding with high-melting-point W metal, the heat-resistance temperature of the W/Ag composite transparent conductive films is increased by 100 °C to 460 °C, and the light transmission and electrical conductivity of the films are not significantly affected. All experimental phenomena in the study are analyzed theoretically. This research can provide an important idea for the metal nanowire electrode, which is difficult to be applied to the photoelectrochemical devices.
传统的银纳米线制备方法由于导电性不佳、复合困难以及耐热性差，无法满足光电器件的苛刻要求。在此，我们基于静电纺丝技术，采用特殊的模板法制备了具有优异性能的银纳米网络。基于银纳米网络的透明导电薄膜在从紫外到可见光的宽范围内具有良好的透光率。重要的是，这些薄膜具有高可操作性，并且易于与其他材料复合。与高熔点的钨金属复合后，W/Ag复合透明导电薄膜的耐热温度提高了100°C，达到460°C，且薄膜的透光率和电导率没有受到显著影响。对研究中的所有实验现象进行了理论分析。该研究可为难以应用于光电器件的金属纳米线电极提供重要思路。
