Fabricating stretchable conductors through simple, cost-effective and scalable methods is a challenge. Here, we report on an approach used to develop nanowelded Ag nanowire/single-walled carbon nanotube (AgNW/SWCNT) hybrid films to be used as high-performance stretchable conductors. Plasmonic welding, which was done at the junctions of AgNWs in order to form hybrid AgNW/SWCNT conductors on an Ecoflex substrate, enabled excellent electrical and mechanical stability under large tensile strains of over 480% without the need to pre-strain. Furthermore, we demonstrate highly stretchable circuits that are used to power LED arrays. The LED arrays are formed using the plasmonic-welded AgNW/SWCNT/Ecoflex hybrid material, which demonstrates suitability for interconnector applications in flexible electronics.
通过简单、经济高效且可扩展的方法制造可拉伸导体是一项挑战。在此，我们报告一种用于开发纳米焊接银纳米线/单壁碳纳米管（AgNW/SWCNT）混合薄膜以用作高性能可拉伸导体的方法。等离子体焊接在AgNW的连接处进行，以便在Ecoflex基板上形成混合AgNW/SWCNT导体，在超过480%的大拉伸应变下实现了出色的电气和机械稳定性，而无需预应变。此外，我们展示了用于为LED阵列供电的高度可拉伸电路。LED阵列使用等离子体焊接的AgNW/SWCNT/Ecoflex混合材料形成，这表明该材料适用于柔性电子中的互连器应用。
