标题：Sustainable conductive coating methodology toward superhydrophobic elastic fabric sensors for human motion monitoring, underwater sensing and photothermal conversion

摘要：The intrinsic hydrophilicity-hydrophobicity mismatch between elastic fabrics and conductive coatings poses dual challenges: poor interfacial adhesion during fabrication and environmental vulnerability in practical use. To address these limitations, we present a sustainable conductive coating methodology to fabricate superhydrophobic conductive elastic fabrics through mussel-inspired adhesion-driven Layer-by-Layer (LBL) assembly using renewable and eco-friendly materials. Our methodology employs a metal-phenolic network (MPN) as a key component to enable robust LBL assembly of cellulose nanofiber-dispersed carbon nanotubes (CNF-CNT) on nylon/spandex (NS) fabric surface to achieve conductive NS fabric, which is then functionalized with octadecylamine to yield superhydrophobic conductive NS fabric (OTCNS) with water contact angle at 152.3°. The OTCNS exhibits excellent stability, resistance to water washing and chemical corrosion, and maintains super hydrophobicity even under 100 % strain. The elastic OTCNS strain sensor exhibits a large sensing range (0–200 %), high sensitivity (GF = 3.26), rapid response time (100 ms), and consistent cyclic stability (>2000 cycles). The OTCNS exhibits efficient photothermal conversion with temperature up to 84.7 °C at a light intensity of 450 mW/cm2. We believe that our innovative approach not only addresses the compatibility and durability challenges of conductive elastic fabrics but also offers a sustainable solution for advanced wearable electronics and smart textiles.
