Abstract

Functional textiles are ideal substrates for wearable electronics. Herein, superhydrophobic, flame-retardant and conductive cotton fabrics were fabricated by sequential assembly of poly(ethylenimine), ammonium polyphosphate and carbon nanotubes, followed by post-treatment with poly(dimethylsiloxane). The resulting fabrics possessed excellent superhydrophobic stability toward acid, alkali, organic solvent, UV irradiation, abrasion and long-time laundering. Meanwhile, when suffering to fire, the coated fabric could generate an efficient char layer and extinguish the fire to protect the cotton fiber from forming flame. Furthermore, this conductive cotton fabric exhibited stable sensing ability in contact with water droplets, showing wide potential application in wearable electronics as multifunctional smart textiles.

通过碳纳米管的逐层组装的超疏水，阻燃和导电棉织物，用于柔性传感电子设备

摘要

功能纺织品是可穿戴电子产品的理想基材。在此，通过依次组装聚乙烯亚胺，聚磷酸铵和碳纳米管来制造超疏水，阻燃和导电的棉织物，然后用聚二甲基硅氧烷进行后处理。所得织物对酸，碱，有机溶剂，紫外线辐射，磨损和长时间洗涤具有优异的超疏水稳定性。同时，当着火时，涂覆的织物可产生有效的炭层并灭火，以保护棉纤维不形成火焰。此外，这种导电棉织物在与水滴接触时表现出稳定的感测能力，在作为多功能智能纺织品的可穿戴电子产品中显示出广阔的应用前景。
