One-Pot Asymmetric Assembly of Hierarchical Triple-Layer Nickel Foam/Titanium Carbonitride MXene Aerogels for Superior Microwave Absorption and Tailored Thermal Management.

ABSTRACT: Rapid strides in portable electronics and telecommunication technologies have sharply escalated the demand for high-performance electromagnetic interference (EMI) shielding materials that effectively suppress secondary electromagnetic pollution while simultaneously integrating thermal management. Here an innovative, lightweight, hierarchical triple-layer aerogel structure comprising nickel (Ni) foam (NiF), titanium carbonitride (Ti₃CNT_x) MXene, and poly(vinyl alcohol) (PVA), fabricated via a facile, one-step bidirectional freeze-casting process is presented. This asymmetric aerogel architecture strategically employs an impedance-matching MXene/PVA top layer for optimized microwave entry, a NiF/MXene/PVA interlayer introducing magnetic loss and enhancing heat conductio
