摘　　要：借鉴染色工艺,采用轧烘焙技术制备了高弹性导电过渡金属碳化物/氮化物(MXene)基罗纹针织物,通过SEM、电阻测试、传感性能测试对其进行了结构和性能表征。结果表明,MXene基罗纹针织物具有较好的弹性和弹性回复性,并且织物中MXene负载量随轧烘焙循环次数的增加而增加,织物电阻随轧烘焙循环次数的增加而降低,最低为38.3Ω/□;织物的应变传感性能测试表明,MXene基罗纹针织物传感性能具有明显的各向异性,并且横列方向的传感性能优于纵行方向。MXene基罗纹针织物横列方向的传感系数和传感区间分别为72.80、0~160%,远高于纵行方向(最大传感系数为4.4,传感区间为0~24%)。Inspired by the dyeing processes,a highly elastic and conductive transition metal carbide/nitride(MXene)-based rib knitting fabric was prepared via a scalable roll-to-roll technology,with its structure and performance characterized and evaluated by SEM,resistance measurement,sensing performance testing.The results showed that MXene-based rib knitting fabric displayed good elasticity and elastic recovery.The MXene loading in the fabric increased and the electrical resistance decreased with roll-to-roll cycles,with the lowest sheet resistance reaching 38.3Ω/□.Data from the strain sensing performance test indicated that the MXene-based rib knitting fabric exhibited anisotropic strain sensing performance,with the strain sensing performance in course direction better than that in the wale direction.In addition,the maximum gauge factor and sensing range were 72.80 and 0~160%,respectively,higher than those in wale direction(gauge factor:4.4,sensing range:0~24%).
