摘要：柔性导电材料是下一代柔性电子设备中不可缺少的组成部分,高性能柔性导电材料的研究和开发对于柔性电子设备的发展具有重要的意义,如:智能手机、电子皮肤、可折叠的电子书、应变传感器以及可拉伸太阳能电池。由铟锡氧化物(ITO)制备的传统的刚性导电材料已经不能满足新型的柔性设备的需求,几种材料被用来取代ITO,包括:石墨烯、碳纳米管、导电高分子以及金属纳米材料。在这几种取代ITO的材料中,银纳米线(Ag NWs)作为一种新型的纳米材料,不仅具备高的电导率,纳米材料的尺寸效应,同时又赋予了其优异的光学性能和柔韧性,使其在柔性导电材料的制备中具有非常广阔的应用前景。主要介绍了Ag NWs在柔性透明电极和可拉伸电极中的应用。首先介绍了Ag NWs柔性透明电极的制备方法和Ag NWs膜的后处理方法,阐述了每种方法的优势和劣势;将Ag NWs与可拉伸基体结合可获得Ag NWs基可拉伸电极,介绍了几种不同形式的Ag NWs基可拉伸电极包括:二维的、三维的以及纤维状的电极,以及不同形式电极对应的制备方法;除此以外,还介绍了通过将Ag NWs与第二导电组分的复合获得性能优异的柔性导电材料,最后对Ag NWs基柔性电极未来的发展进行了展望。
Flexible and conductive materials (FCMs) are the key building blocks of next-generation electronics such as smart phone, E-skins, folding E-books, strain sensors as well as stretchable solar cell. Thus, fabricating high-quality FCMs is of great importance to the development of future flexible electronics. Traditional conductive materials are mainly prepared by indium tin oxide (ITO) which is rigid and could not satisfy the needs of novel flexible electronics. Several materials have been applied to replace ITO in the fabrication of flexible electrodes including graphene, carbon nanotubes, conducting polymer and metal nano-materials. Among all the alternatives of ITO, silver nanowires (AgNWs), as a novel nano-material, inherited the high electrical conductivity from metal Ag. Besides, the nanometer-sized effect imparts AgNWs both excellent optical property and flexibility, which endows it great potential in the application of FCMs. This review separately illustrates flexible transparent electrodes (FTEs) and stretchable electrodes based on AgNWs. For AgNWs-based FTEs, several coating methods and the post-treatment of AgNWs-based FTEs such as high-temperature annealing and mechanical pressing were introduced and the advantage and disadvantage of each method were stated. In addition, AgNWs-based stretchable electrodes could be prepared by integrating AgNWs with stretchable matrices. Here, AgNWs-based electrodes with different shapes were introduced in detail including two-dimensional, three-dimensional as well as fibrous electrodes and their fabrication methods were also presented. Meanwhile, AgNWs are composed of a second electrically conductive material to obtain flexible electrodes with more excellent performance. Finally, the future developments of AgNWs-based FCMs were proposed.
