In this paper, a multifunctional slippery polydimethylsiloxane/carbon nanotube composite strain sensor (SPCCSS) is prepared using a facile template method. Benefitting from the slippery surface, the SPCCSS shows excellent liquid repellence properties, which can repel various liquids such as oil, cola, yogurt, hot water and some organic solvents. Meanwhile, the SPCCSS has a large strain sensing range (up to 100%), good sensitivity (GF = 3.3) and stable response with 500 cyclic stretches under 20% strain. Moreover, it is also demonstrated that the SPCCSS displays outstanding corrosion resistance (from pH = 1 to pH = 14) and anti-icing (8 min at -20 °C)/photothermal deicing (104 s with NIR power density of 1 W/cm) properties, broadening its application in extreme acid, alkali and low-temperature conditions. Therefore, the multifunctional SPCCSS with the liquid repellence, anti-corrosion, and anti-icing/deicing properties has potential applications in wearable human motion monitoring tools under complex harsh environments.
本文采用简便的模板法制备了一种多功能超滑聚二甲基硅氧烷/碳纳米管复合应变传感器（SPCCSS）。得益于其超滑表面，SPCCSS表现出优异的拒液性能，能够排斥各种液体，如油、可乐、酸奶、热水和一些有机溶剂。同时，SPCCSS具有较大的应变传感范围（高达100%）、良好的灵敏度（GF = 3.3），并且在20%应变下进行500次循环拉伸时响应稳定。此外，还证明了SPCCSS具有出色的耐腐蚀性（pH值从1到14）和抗结冰（在-20°C下8分钟）/光热除冰（在近红外功率密度为1 W/cm²时104秒）性能，拓宽了其在极端酸碱和低温条件下的应用范围。因此，具有拒液、抗腐蚀和抗结冰/除冰性能的多功能SPCCSS在复杂恶劣环境下的可穿戴人体运动监测工具中具有潜在应用。
