In response to the growing challenges posed by increasingly severe electromagnetic radiation environments and diverse personal thermoregulation requirements, development of wearable devices integrating interference (EMI) shielding thermal management functionalities has become critical for enhancing human comfort safety. Inspired hierarchical structure natural leaves, we present a multifunctional material composed MXene/polyaniline (PANI)/polydopamine (PDA) on flexible activated carbon fabric (ACC) substrate. This is fabricated through facile yet efficient mixed-dimensional assembly strategy, combining two-dimensional (2D) MXene nanosheets with one-dimensional (1D) PANI. The architecture mimics biological ACC serving as robust xylem-like substrate, PANI acting phloem-like supporting layer, forming protective outer layer. amino groups ( (−NH2) function binding sites, facilitating formation hydrogen bonds both PDA MXene, thereby interfacial adhesion mechanical stability. Furthermore, synergistic combination PANI's inherent conductivity MXene's exceptional electrical properties significantly improves overall conductive network fabric. resulting MXene/PANI/PDA@ACC (MPPA) demonstrates outstanding performance, including high (384.6 S/m), superior EMI effectiveness (average 45.81 dB), Joule heating (reaching 94 °C at 5 V), excellent camouflage capabilities (infrared emissivity 0.421). Notably, retains flexibility, durability, breathability, moisture permeability, ensuring even under complex environmental conditions. These combined position MPPA promising candidate next-generation technologies, addressing dual demands protection adaptive management.
