智能纺织品

Abstract(#br)Smart textile devices have now received increasing attention for potential application in wearable human motion monitoring, healthcare and personal thermal management. MXene (Ti 3 C 2 T x ), which is a new two-dimensional material with remarkable properties, has been widely applied in wearable electronics. However, it remains a challenge to prepare MXene based smart textile that possesses multifunctional wearable sensing applications and can also keep MXene from oxidizing.

智能纺织设备在可穿戴式人体运动监测、医疗和个人热管理方面的潜在应用日益受到关注。MXene ( Ti3C2Tx )是一种性能优异的新型二维材料，在可穿戴电子领域得到了广泛的应用。然而，制备具有多功能可穿戴传感应用且能使MXene不被氧化的MXene基智能纺织品仍是一个挑战。这里，我们通过构建多重核壳结构，即在聚多巴胺( PDA )改性弹性纺织品上进行MXene装饰，然后用聚二甲基硅氧烷( PDMS )涂层，制备出防水透气的智能纺织品。MXene包裹纤维形成导电网络，PDMS不仅能保护MXene不被氧化，还能赋予纺织品超疏水性能和耐腐蚀性。该智能纺织品具有突出而持久的光热和电热转换性能。更重要的是，纺织电子表现出灵敏稳定的应变传感性能和温度传感能力，具有较高的热阻系数。显然，这种智能纺织设备在下一代全合一的可穿戴电子设备中具有很高的应用前景。
