透明导电材料是光电器件的重要组成部分。金属纳米线网络具有全光谱透过率高、导电性好、耐弯折等特点，是替代传统透明导电金属氧化物的理想材料。目前，提高金属纳米线网络的承载电流能力和抗氧化能力是拓展其应用范围和使役性能的关键。本项目旨在利用焦耳热辅助燃烧法在铜纳米线表面选择性沉积AZO壳层，通过调控AZO壳层的晶体结构和Cu/AZO核壳界面的化学键性质，提高界面处金属和氧离子的迁移和扩散激活能，获得低成本、高稳定性的Cu/AZO核壳纳米线网络透明导电材料。研究燃烧法的前驱体配比和电流输入方式对AZO壳层的晶体结构、Cu/AZO界面原子成键性质、以及Cu/AZO核壳纳米线网络的光学和电学性质的调控规律；利用理论模拟、原位表征手段、变温电学测试，揭示AZO壳层厚度和结晶性、核壳界面性质对铜纳米线网络承载电流能力和抗氧化能力的影响机理。本项目为提高金属纳米线网络透明导电材料的稳定性提供新思路。

Transparent conductive materials are an important part of optoelectronic devices. Metal nanowire network (MNN) has the characteristics of high transmittance, high electrical conductivity and good flexibility, and is regarded as an ideal material to replace the traditional transparent conductive metal oxides. At present, improving the current carrying capacity and oxidation resistance of MNN is the key to expand its application range and service lifetime. This project aims to prepare a low-cost, high-stability Cu/AZO core/shell nanowire network transparent conductive material by using Joule heat-assisted combustion method which can selectively deposit AZO on the surface of Cu nanowires. The migration and diffusion activation energy of metal and oxygen ions at the Cu/AZO core/shell interface will be improved by regulating the chemical bond properties of Cu/AZO and the crystal structure of AZO shell. We will investigate the effect of combustion reaction precursor ratio and input power on the crystal structure of the AZO shell, and the optoelectronic performance of the Cu/AZO core/shell nanowire network. The in-situ characterization, theory simulation and temperature-dependent electrical test will be carried out to reveal the influence mechanism of AZO shell thickness and crystallinity, and Cu/AZO interface properties on the stability of copper nanowire network. This project provides a new idea for improving the stability of MNN transparent conductive materials.
