Materials that retain a high conductivity under strain are essential for wearable electronics. This article describes a conductive, stretchable composite consisting of a Cu–Ag core–shell nanowire felt infiltrated with a silicone elastomer. This composite exhibits a retention of conductivity under strain that is superior to any composite with a conductivity greater than 1000 S cm–1. This work also shows how the mechanical properties, conductivity, and deformation mechanism of the composite changes as a function of the stiffness of the silicone matrix. The retention of conductivity under strain was found to decrease as the Young’s modulus of the matrix increased. This was attributed to void formation as a result of debonding between the nanowire felt and the elastomer. The nanowire composite was also patterned to create serpentine circuits with a stretchability of 300%.

铜银纳米线毡制可拉伸导电复合材料
在应变下保持高导电性的材料对于可穿戴电子设备至关重要。本文介绍了一种导电的，可拉伸的复合材料，该复合材料由浸有有机硅弹性体的Cu-Ag核-壳纳米线毡组成。该复合材料在应变下的电导率保持率优于任何电导率大于1000 S cm –1的复合材料。。这项工作还显示了复合材料的机械性能，电导率和变形机理如何根据有机硅基质的硬度而变化。发现在应变下电导率的保留随着基质的杨氏模量增加而降低。这归因于由于纳米线毡和弹性体之间的脱粘而形成的空隙。纳米线复合材料也被图案化以产生具有300％可拉伸性的蛇形电路。
