Rapid advances in modern electronics place ever-accelerating demands on innovation towards more robust and versatile functional components. In the flexible electronics domain, novel material solutions often involve creative uses of common materials to reduce cost, while maintaining uncompromised performance. Here we combine a commercially available paraffin wax-polyolefin thermoplastic blend (elastomer matrix binder) with bulk-produced carbon nanofibres (charge percolation network for electron transport, and for imparting nanoscale roughness) to fabricate adherent thin-film composite electrodes. The simple wet-based process produces composite films capable of sustained ultra-high strain (500%) with resilient electrical performance (resistances of the order of 10(1)-10(2) Ω sq(-1)). The composites are also designed to be superhydrophobic for long-term corrosion protection, even maintaining extreme liquid repellency at severe strain. Comprised of inexpensive common materials applied in a single step, the present scalable approach eliminates manufacturing obstacles for commercially viable wearable electronics, flexible power storage devices and corrosion-resistant circuits.

用于低成本超柔电子产品的极易拉伸和导电的憎水涂料。

随着现代电子技术的飞速发展，对更强大，功能更多的功能部件的创新提出了越来越高的要求。在柔性电子领域，新颖的材料解决方案通常涉及创造性地使用普通材料以降低成本，同时又保持不妥协的性能。在这里，我们将市售的石蜡-聚烯烃热塑性共混物（弹性体基体粘合剂）与批量生产的碳纳米纤维（用于电子传输和赋予纳米级粗糙度的电荷渗滤网络）相结合，以制造粘附的薄膜复合电极。简单的基于湿法的工艺可生产出能够承受超高应变（500％）且具有弹性电性能（电阻为10（1）-10（2）Ωsq（-1）数量级）的复合膜。该复合材料还被设计为具有超疏水性，可长期保护腐蚀，即使在严重应变下也能保持极高的拒液性。本发明的可扩展方法由在单个步骤中应用的便宜的常用材料组成，消除了商业上可行的可穿戴电子设备，柔性功率存储设备和耐腐蚀电路的制造障碍。
