Progress of Metal Mesh Transparent Electrodes Fabraicated by Polymer Patterning Network

高分子网状图案结合不同的金属化方法是制备金属网格透明电极(MMTE)的常用策略。高分子网状图案制备的要点在于线宽和孔隙率的控制,上述参数与MMTE光电性能直接相关。文中综述了高分子网状图案的制备方法及其在MMTE中的应用。目前,高分子静电纺丝网状图案应用较广,可实现低成本、大面积制备MMTE。为了得到高性能的MMTE,需要降低MMTE金属线的宽度/高度(W/H)比值。新兴可穿戴器件要求MMTE具有可伸缩性。进一步对有望用于制备这类MMTE的蛇形图案、剪纸图案、分形图案进行了介绍。

Polymer network patterning combined with various metallization methods is a common strategy to prepare metal mesh transparent electrodes(MMTE).To control the line width and aperture area fraction is the critical issue of fabricating polymer network patterns.The two parameters are directly related to the photoelectric performance of MMTE.This paper reviewed the preparation methods of polymer network patterns and their applications in MMTE.At present,the polymer electrospun networks can prepare large-area MMTE at a low cost.Decreasing the width/height(W/H)ratio of MMTE metal wires is necessary to obtain high-performance MMTE.Emerging wearable devices require MMTE to be stretchable.The possible patterns that meet this trend were also introduced,including serpentine patterns,kirigami patterns,and fractal patterns.
