摘要

Incorporating conductive materials into the fabric structure for flexible wearable applications has aroused extensive research attention in recent years. Although flexible wearable sensors based on textiles make important strides towards the achievement of flexible wearable devices, most of the reported flexible strain sensors still have some limitations, with special reference to the manufacture of the sensitivity, and durability of these sensors with subtle- and large-scale workable strain sensing ranges on an industrial scale. Herein, a flexible strain sensor was fabricated to generate carboxylated carbon nanotubes (CNTs-COOH) and silver nanoparticles (AgNPs) respectively on the polydopamine (PDA)-templated nylon/polyurethane (nylon/PU) fabric surface via a dipcoating technique and liquid-phase chemical adsorption reduction process. The surface morphology and chemical structure of the fabricated nylon/PU fabric were investigated by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). Interestingly, CNTs-COOH and AgNPs were successfully coated onto the PDA-templated nylon/PU fabric (PNPF). Furthermore, the as-prepared strain sensor exhibited fascinating performances, containing high sensitivity, suitable stability under different strains, remarkable electrical conductivity because of the depositing of conductive fills, exceptional durability over 1000 cycles, and outstanding electrical heating property. Importantly, the proposed strain sensor was demonstrated to be used for human motion including tiny human movement and robust body motion or temperature detection, indicating its further desirable application in flexible wearable devices.
