高质量超长银纳米线的控制合成及其在透明网络电极中的应用

Due to the excellent conductivity, light-admitting quality, and flexibility, silver nanowires have been regarded as the most promising candidate to replace indium tin oxide (ITO). However, controllable synthesis of high-quality silver nanowires has always been the main obstruction of their large-scale applications. This project thereby aims at the important scientific problem of controllable synthesis of silver nanowires and the demand of their application in transparent electrodes. A new method about cooperation between anion and cation additives will be adopted for the synthesis of high-quality ultra-long silver nanowires, and then the transparent electrodes will be fabricated based on it. Meanwhile, the formation and control mechanism of high-quality ultra-long silver nanowires and the structure-performance relationship between nanowirestransparent electrodes will be deeply revealed through microstructure characterization. The implementation of this project will not only offer important reference to the research on controllable synthesis and formation mechanism of high-quality silver.nanowires, but also provide important academic guide to their applications in the new generation transparent conductive films.

银纳米线由于具有优异的导电、透光及耐挠曲等特性，因此被视为最具潜力的氧化铟锡（ITO）替代材料。然而，高质量银纳米线的可控制备一直以来都是其大规模应用的主要障碍。鉴于此，本项目瞄准当前银纳米线控制合成所面临的重要科学问题及其在透明电极领域中的应用要求，拟采取阴阳离子双助剂协同作用的新方法以合成出高质量的超长银纳米线，进而制作出相应的透明电极；与此同时，结合微观结构表征手段深入揭示高质量超长银纳米线的形成与控制机理以及纳米线—透明电极间的构效关系。项目的实施不仅为高质量银纳米线的可控合成及形成机理研究提供重要参考，而且对其在新一代透明导电薄膜中的应用具有重要的理论指导价值。
