摘要:

银纳米线(Ag NWs)是制备柔性透明电极(TCs)的重要材料, 但目前使用多元醇还原法合成的Ag NWs直径较大, 影响所得Ag NWs薄膜的光学和电学性能. 本文利用MXene辅助合成Ag NWs, 通过控制纳米片尺寸实现了不同直径Ag NWs的生长. 利用高分辨透射电子显微镜(HRTEM)研究了其生长机制, 揭示了MXene同时作为还原剂和成核剂的重要作用. 本工作发现MXene作为一种新型二维层状材料可用于辅助合成高质量 Ag NWs, 使其有望成为新一代高性能柔性透明电极材料.

Abstract:

Silver nanowires(Ag NWs) are important materials for next-generation transparent conductors(TCs). However, Ag NWs synthesized by polyol reduction have large diameters, which affects the optical and electrical properties of Ag NWs thin films. Herein, we propose a new method for the synthesis of Ag NWs using MXene, and the growth of Ag NWs with different diameters can be achieved by controlling the size of nanosheets. The growth mechanism was studied by high-resolution transmission electron microscopy(HRTEM), revealing the important role of MXene as both a reducing and nucleating agent. Therefore, our work exhibits that as a novel two-dimensional layered material, MXene is helpful for the synthesis of high-quality Ag NWs, making them a new-generation material for high-performance flexible transparent electrode.

Key words: Titanium carbide, Silver nanowire, Reducing agent, Nucleating agent, Flexible transparent electrode
