Abstract
The practical application of MXene-based wearable electronics is often hindered by poor interfacial adhesion and environmental instability. This study addresses these challenges through a bioinspired interfacial design on mechanically robust aramid textiles. By synergistic coupling of H2O2/plasma surface activation with a polydopamine (PDA)/polyethylenimine (PEI) polyelectrolyte bridge, we achieved highly uniform MXene loading and strengthened interfacial bonding. The optimized conductive textiles exhibit a low electrical resistance (<20 Ω cm–2), excellent washing durability, and retained breathability (∼4100 g m–2 day–1 water vapor transmission rate). Furthermore, a hydrophobic silica coating was integrated to achieve a 130° water contact angle, protecting the MXene from moisture-induced degradation. Beyond its stability, the fabric serves as a high-performance platform for strain sensing, electromagnetic interference (EMI) shielding (∼21 dB), and infrared thermal camouflage, establishing a comprehensive strategy for durable and water-tolerant multifunctional wearable systems.
