结合联合收割机弹性与电子或光电性能的器件的出现为应用提供了令人兴奋的新机会，但也带来了重大的材料挑战。在这里，我们报告的弹性聚合物发光器件（EPLED）的制造使用一个简单的，所有的解决方案为基础的过程。EPLED的特征在于一对透明复合电极，其包括镶嵌在表面层中的银纳米线的薄渗透网络。所得到的EPLED在室温下表现出橡胶弹性，是可折叠的，并且当暴露于高达120%的应变时可以发光。它也可以在重复的连续拉伸循环中存活，并且小的拉伸被证明可以显着提高其发光效率。制造过程是可扩展的，并且容易地适于以5x5像素阵列为特征的简单无源矩阵单色显示器的演示。
The emergence of devices that combine elasticity with electronic or optoelectronic properties offers exciting new opportunities for applications, but brings significant materials challenges. Here, we report the fabrication of an elastomeric polymer light-emitting device (EPLED) using a simple, all-solution-based process. The EPLED features a pair of transparent composite electrodes comprising a thin percolation network of silver nanowires inlaid in the surface layer. The resulting EPLED, which exhibits rubbery elasticity at room temperature, is collapsible, and can emit light when exposed to strains as large as 120%. It can also survive repeated continuous stretching cycles, and small stretching is shown to significantly enhance its light-emitting efficiency. The fabrication process is scalable and was readily adapted for the demonstration of a simple passive matrix monochrome display featuring a 5x5 pixel array.
