Abstract

Silver nanowires (Ag NWs) is a potential material to be used as the transparent conductive electrode (TCE) material, in the flexible electronic applications. The polyol method is the commonly used technique to synthesis the silver nanowires. The growth of the silver nanowires is facilitated by the oxidative etching of the silver seed particles. The present work investigates the influence of the manganese(II) ions to promote the growth of silver nanowires. The manganese(II) ions, due to its multiple oxidation states, play an essential role in removing the dissolved atomic oxygen, which prevent the growth of longer nanowires. Its effect on the length and diameter of the silver nanowires is studied in detail with different concentration levels. Characterization tools, such as X-ray diffractometry, electron microscopy (FESEM and TEM) and UV–VIS spectroscopy are used to characterise the synthesised silver nanowires. The addition of manganese(II) ions alters the aspect ratio of the silver nanowires that in turn, affects the optoelectrical properties of the TCE films. By using the synthesised silver nanowires, transparent heaters are successfully fabricated and their performances under different conditions are evaluated.

锰离子对多元醇合成银纳米线形貌的有益影响

摘要

银纳米线（Ag NWs）是一种潜在的材料，在柔性电子应用中可用作透明导电电极（TCE）材料。多元醇法是合成银纳米线的常用技术。银种子颗粒的氧化蚀刻促进了银纳米线的生长。本工作调查锰（II）离子对促进银纳米线生长的影响。锰（II）离子由于其多种氧化态，在去除溶解的原子氧方面起着至关重要的作用，从而阻止了更长的纳米线的生长。在不同浓度水平下，详细研究了其对银纳米线长度和直径的影响。表征工具，例如X射线衍射仪，电子显微镜（FESEM和TEM）和UV-VIS光谱用于表征合成的银纳米线。锰离子的加入改变了银纳米线的纵横比，进而影响了TCE薄膜的光电性能。通过使用合成的银纳米线，成功制造了透明加热器，并评估了它们在不同条件下的性能。
