中文摘要: 银纳米线材料有望替代ITO用于制备柔性透明电极材料。但传统涂覆法制备银纳米网为"搭接"结构,未能充分发其低电阻特性。本项目拟采用电磁感应技术对银纳米线交叉处进行熔融焊接,组装银纳米网。设计合成不同直径的银纳米线,研究电磁环境下银纳米线尺寸与感生电流间的内在关系;通过改变磁场强度、紧实程度等因素,研究纳米网中感生电流密度的分布规律,建立银纳米线结构与电极性能之间的调控模型;在此基础之上,结合分子动力学理论,构建电磁场中银纳米网自组装过程的理论模型。本项目拟阐明电磁环境下银纳米网组装过程的机制与调控策略,为探索新型柔性透明电极材料提供理论与技术指导。

英文摘要: Sliver nanowire(AgNW) networks has been a potential soft transparent conductive electrode(TOC) material, which can be the candidate for indium tin oxide(ITO). However, AgNW networks show high resistance because of its crossed strcutrure, prepared by coating method. In this proposal, electromagnetic resonance technology(ERT) will be used to weld and assemble AgNW networks. The relationship between diameter and induced current will be researched with different AgNW. The influence of structure and induced current on properties of AgNW will be concluded by the following researchwork. Moreover, the welding mechanism of ERT will be described by the molecular dynamics model. All these lay a theoretical and experimental foundation for the development of soft TOC.
