摘　　要：随着柔性电子领域的不断发展,人们对可穿戴设备的智能化需求逐渐增多。其中,具有视觉交互功能的智能发光纺织品因其应用场景和功能的多样性引起了人们的广泛关注。ZnS∶Cu基力致发光弹性体仅在受到机械应力下就可以实现可见光的发射,具备可循环的力-光可视化传感特性,在智能发光服装方面有着潜在的应用价值。本文通过弹性聚合物基体网络结构调控、Al_(2)O_(3)纳米粒子掺杂的方法来增加应力传递位点,从而提高ZnS∶Cu复合弹性体的发光强度。通过挤出包覆、3D打印、丝网印刷等工艺实现了力致发光智能织物的连续化和图案化制备,改善了力致发光纺织品的力-光转换的灵敏度和穿戴舒适性问题,其在可穿戴传感、运动健康监测、智慧交通警示等方面具有潜在的应用价值。With the rapid development of flexible wearable electronics,the demand for intelligent wearable devices has remarkably increased.Smart luminescent clothing with the ability of visual interaction has attracted wide attention due to its versatile functions.Elastico-mechanoluminescent materials such as ZnS∶Cu mechanoluminescent elastomers have potential applications in smart luminescent cloths/garments because of their repeatable force-to-light visualized sensing capabilities.In this work,we increased the stress transfer sites in ZnS∶Cu mechanoluminescent elastomers through tunning the network structure of the elastic polymer matrix and the doping of Al_(2)O_(3)nanoparticles,thus improved the luminescence intensity of the mechanoluminescent elastomer.The continuous and patterned preparation of mechanoluminescent textile has also been achieved through extrusion coating,3D printing,and screen printing mechanoluminescent elastomers on traditional textiles.The sensitivity and wearing comfort of the luminescent woven textiles have therefore been improved,which provides potential value for this mechanoluminescent elastomers in applications including wearable sensing,health monitoring,traffic warning,etc.
