与易碎的氧化铟锡（ITO）薄膜相比，透明导体（tc）能够承受高机械变形，这对于具有严格耐候性要求的柔性和可拉伸显示器、标牌系统、照明设备和太阳能电池板的卷对卷生产至关重要。本文报道了一种由核-壳纳米纤维网组成的高度可拉伸的TC，它模仿了自然系统的纤维结构，如叶子的静脉或神经系统。在重复拉伸中，TC网具有高透明度，低片材阻力和前所未有的拉伸性和稳定性。纳米纤维TC网可以转移到不同的衬底上，这表现在转移到有机太阳能电池上，显示出与ITO电极器件相当的光伏性能。这项工作提出了一个技术平台，可扩展用于制造大面积透明导体，用于柔性和可拉伸的显示器、电子产品和太阳能电池，这些导体位于橡胶、织物和纸张等非传统基板上。
The need for transparent conductors (TCs) that are capable of withstanding high mechanical deformation in comparison to the brittle indium tin oxide (ITO) films is paramount for roll‐to‐roll production of flexible and stretchable displays, signage systems, lighting devices and solar panels with stringent weatherability requirements. This paper reports a highly stretchable TC comprising of a web of core‐shell nanofibers, which mimics the fibrous structure of natural systems such as veins of a leaf or nerve systems. The TC web demonstrates high transparency, low sheet resistance, and unprecedented stretchability and stability over repeated stretching. The nanofiber TC web can be transferred to different substrates, which is manifested by the transfer onto an organic solar cell, demonstrating a photovoltaic performance comparable to that of a device with an ITO electrode. This work presents a technological platform, scalable for the manufacturing of large area transparent conductors for flexible and stretchable displays, electronics and solar cells on unconventional substrates such as rubber, fabric and paper.
