研制了一种由核壳结构铜纳米线网络和可修复聚氨酯护套组成的自修复柔性透明导体。通过Diels-Alder反应将含呋喃环的聚氨酯预聚物与N，N′-（4，4 ′-亚甲基二苯基）双马来酰亚胺交联，形成可愈合的网络聚合物。该薄聚合物层焊接铜纳米线并将纳米线网络限制在衬底表面上。纳米复合导体在550 nm处的薄层电阻为22.3 Ω sq− 1，透射率为66.5%。在120 °C下，3 min内可恢复98%的表面电导率，在同一位置可重复5次损伤-愈合行为。目前的工作提供了一种简单的方法来制造先进的柔性透明导体。
A self-healing flexible transparent conductor comprising a core-shell copper nanowire network and healable polyurethane sheath was developed. The polyurethane pre-polymer containing furan rings was cross-linked withN,N′-(4,4′-methylenediphenyl) dimaleimide via a Diels-Alder reaction to form the healable network polymer. This thin polymer layer solders the copper nanowires and confines the nanowire network on the substrate surface. The nanocomposite conductor exhibits a sheet resistance of 22.3 Ω sq−1with 66.5% transmittance at 550 nm. 98% of the surface conductivity can be recovered in 3 min at 120 °C, and the damaging-healing behavior could be repeated 5 times at the same position. The present work provides a simple way to fabricate advanced flexible transparent conductors.
