Abstract

A highly stretchable and foldable conductive cord was developed by depositing silver nanowires (AgNWs) on a polyurethane cord. The application of pre-strain to the cord during the deposition of AgNWs resulted in the formation of a wrinkled AgNW layer, thereby inducing structural stability towards stretching and bending. This conductive cord exhibited stable electric conduction under strain values of up to 167% and at a bending radius of 0.3 mm. Also, it could withstand a stretching test of 500 cycles at a strain of 50%.

摘要

一种高拉伸和可折叠的导电绳是通过在聚氨酯绳上沉积银纳米线（AgNWs）制成的。在沉积 AgNWs 的过程中对绳子施加预应变导致形成褶皱的 AgNW 层，从而使结构对拉伸和弯曲具有稳定性。这种导电绳在应变值高达 167%和弯曲半径为 0.3 毫米的情况下表现出稳定的导电性能。此外，它可以在 50%的应变下承受 500 次拉伸测试循环。
