There is an increasing demand for eco-friendly and sustainable electronics, where recycling of functional materials is the key. Soft electronics have received much attention recently, however, their recycling has been challenging. Here a strategy is reported to recycle silver nanowire (AgNW) percolation network to achieve sustainable soft electronics. The effect of working solvent and ultrasonication time on the morphology and electrical properties of the recycled AgNW network is investigated. Using the selected working solvent with low surface tension (isopropanol) and optimal ultrasonication time (20 s), the AgNW network film can be recycled multiple times (four times in this work) without significant morphology changes and performance degradation. A transient epidermal sensor patch using AgNW as electrodes and a water-soluble polymer substrate is fabricated and fully recycled. On-body test of the epidermal sensor patch fabricated by recycled AgNWs demonstrates a working example for the recycling concept of AgNWs. The recycling concept can be extended to other nanomaterials in the form of percolation network.

用于可持续软电子的纳米线渗透网络的回收

对环保和可持续电子产品的需求不断增加，其中功能材料的回收是关键。软电子最近受到了很多关注，然而，它们的回收利用一直具有挑战性。据报道，一种策略是回收银纳米线（AgNW）渗透网络以实现可持续的软电子。研究了工作溶剂和超声处理时间对再生 AgNW 网络的形态和电性能的影响。使用选定的具有低表面张力（异丙醇）和最佳超声处理时间（20 秒）的工作溶剂，AgNW 网络膜可以多次循环使用（本工作中为四次），而不会发生显着的形态变化和性能下降。使用 AgNW 作为电极和水溶性聚合物基板制造并完全回收的瞬态表皮传感器贴片。由回收的 AgNW 制造的表皮传感器贴片的在体测试展示了 AgNW 回收概念的工作示例。回收概念可以以渗透网络的形式扩展到其他纳米材料。
