我们报告了一个简易的，溶液相路线大规模制造和表征的单晶氧化铜纳米线具有可控的直径，不同的形态，和高的纵横比。通过在水热条件下用邻茴香胺、吡咯或2，5-二甲氧基苯胺还原醋酸铜来合成Cu 2 O纳米线。单个Cu 2 O纳米线的电学性质已经通过I-V特性进行了检查。Cu 2 O/聚（2，5-二甲氧基苯胺）核/壳纳米线的输出特性表现为n型特性和提高的导电性，而Cu 2 O纳米线的输出特性为线性。这项研究的结果提供了一种低成本、天然丰富的纳米结构材料，可用于电子设备。
We report a facile, solution-phase route to large-scale fabrication and characterization of single crystalline Cu2O nanowires with controllable diameter, different morphologies, and high aspect ratios. The synthesis of Cu2O nanowires is achieved by the reduction of cupric acetate with o-anisidine, pyrrole, or 2,5-dimethoxyaniline under hydrothermal conditions. The electrical properties of individual Cu2O nanowires have been examined by I−V characteristics. The output properties of Cu2O/poly(2,5-dimethoxyaniline) core/shell nanowires show n-type characteristics and improved conductivity, while those of Cu2O nanowires are linear. The results from this study provide a low-cost, naturally abundant nanostructured material for use in electronic devices.
