低表面粗糙度及高粘附力Ag-NW透明电极的制备及应用

基于银纳米线（Ag-NW）的透明电极由于其优良的导电性、透光性以及机械柔韧性而受到了广泛的关注。本项目针对Ag-NW透明电极面临的高表面粗糙度以及Ag-NWs与基底之间低的粘合力等问题。提出了光辅助多元醇还原法合成小直径的Ag-NW，结合界面组装制备有序排列的Ag-NW阵列用于降低其表面粗糙度；而后将Ag-NW阵列分两次转移至载有半固化的聚二甲基硅氧烷（PDMS）的透明基底上形成“十”字交叉的网格，再将PDMS完全固化用于提高Ag-NWs与基底之间的粘合力。设计并构建基于Ag-NW透明电极的光电器件（如光伏太阳能电池），探索Ag-NW透明电极表面粗糙度和粘附力对器件性能的影响，揭示Ag-NW透明电极在柔性光电器件中的应用价值。为Ag-NW透明电极的商业化应用奠定基础，促进柔性可穿戴光电器件的发展。

The transparent electrode (TEs) based on silver nanowire (Ag-NW) have received considerable attention because of their outstanding electrical, optical, mechanical properties. In terms of the challenges faced by Ag-NW TEs such as high surface roughness and poor adhesion of Ag-NWs on the substrate, we propose a Photo-assisted polyol reduction method to synthesize Ag-NWs with a thin diameter. Then, we also assemble Ag-NWs into the well-aligned arrays to reduce the surface roughness of Ag-NW TEs. Subsequently, the well-aligned Ag-NW arrays are transferred to a transparent substrate with semi-cured PDMS twice to form a crisscross Ag-NW network, and the PDMS is further solidified to improve the adhesion between silver nanowires and substrate. The optoelectronic devices based on Ag-NW TEs are designed to explore the influence of surface roughness and adhesion between Ag-NWs and the substrate on the optoelectronic properties, and the application value of Ag-NW TEs in the optoelectronic devices is revealed. This proposal aims to lay the foundation for the commercial application of Ag-NW TEs and promote the development of flexible wearable optoelectronic devices.
