Abstract

Smart textile-based wearable devices show promising application prospects for detecting NH₃ concentrations in environmental and health monitoring. However, mechanical loads and aqueous environments during use can damage the interface between the textile fiber and the sensing layer, posing a challenge to the reliable performance of textile-based sensors. Herein, inspired by the adhesion chemistry of mussels, we report a fatigue-resistant, washable, and environmentally friendly smart textile (PANI-PDA-BF) for monitoring NH₃. This smart textile utilizes natural bamboo fiber (BF) cloth as the substrate, with a polydopamine (PDA) coating to enhance the bonding performance of the polyaniline (PANI) sensing layer to the bamboo fiber, thereby improving fatigue resistance and washability. Experimental results demonstrate that the sensitivity of PANI-PDA-BF only reduced by 11 % and 22 % after 10,000 tensile cycles and 30 min of washing deionized water, which is much lower than the 51 % and 48 % of PANI-BF (without PDA coating). Additionally, PANI-PDA-BF exhibits outstanding environmental-friendly due to the inherent biodegradation of PDA and BF. PANI-PDA-BF's exceptional NH₃ sensing performance, durability, and environmental-friendliness make it an up-and-coming candidate for NH₃ monitoring wearable devices.

贻贝启发水洗，耐疲劳，环保智能纺织品监测NH3

基于智能纺织品的可穿戴设备在环境和健康监测中检测NH3浓度具有广阔的应用前景。然而，在使用过程中，机械载荷和水环境会破坏纺织纤维与传感层之间的界面，对纺织传感器的可靠性能提出了挑战。在这里，受贻贝粘附化学的启发，我们报告了一种耐疲劳、可洗涤、环保的智能纺织品（PANI-PDA-BF），用于监测NH₃。这种智能纺织品以天然竹纤维（BF）布为基材，采用聚多巴胺（PDA）涂层，增强聚苯胺（PANI）传感层与竹纤维的粘合性能，从而提高抗疲劳性和耐洗性。实验结果表明，经过10000次拉伸循环和30 min的去离子水洗涤后，聚苯胺-PDA- bf的灵敏度分别下降了11%和22%，远低于聚苯胺- bf（未涂PDA）的51%和48%。此外，由于PDA和BF本身的生物降解特性，聚苯胺-PDA-BF具有良好的环境友好性。PANI-PDA-BF卓越的NH3传感性能，耐用性和环保性使其成为NH3监测可穿戴设备的热门候选产品。
