High-performance ZnS∶Cu Based Mechanoluminescent Elastomers and Their Applications in Visually Interactive Fabrics

Abstract： 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 in• teraction has attracted wide attention due to its versatile functions.Elastico-mechanoluminescent materials such as ZnS∶Cu mechanoluminescent elastomers have potential applications in smart lumi• nescent 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，
