• • Centrifugal casting at 4000 r/min increases Herman's orientation factor from 0.681 to 0.794, a 16.6% improvement, directly enhancing anisotropic properties critical for EMI shielding and thermal management.
• • Tensile strength and toughness of MXene/PVA films rise from 55.2 to 191.1 MPa and from ~0.8 to 2.5 MJ/m³, respectively, representing a 246% increase in strength and 213% in toughness, enabling robust flexible electronics.
• • The optimized film achieves an absolute EMI shielding effectiveness (SSE/t) of 21029 dB cm²/g at ~8 μm thickness, surpassing many reported materials and meeting stringent lightweight shielding requirements.
• • Infrared emissivity is reduced to 0.248, a significant decrease from typical values, enabling effective thermal camouflage for stealth applications in defense and energy-efficient buildings.
