This study presents a novel approach to fabricate stretchable, transparent, and ultra-broadband (0.1–10 THz) terahertz (THz) shielding MXene (Ti₃C₂Tx) films using a wrinkled structure engineering strategy. The films exhibit enhanced conductivity and surface plasmon resonances, leading to improved THz wave absorption. The wrinkled MXene films show a 36.5% increase in electromagnetic interference (EMI) shielding efficiency (SE) compared to flat films, with an EMI SE of 21.1 dB at a thickness of 100 nm and an average EMI SE/t of 700 dB μm⁻¹ over the 0.1–10 THz range. The wrinkled structure also enhances the stretchability and stability of the films, maintaining low THz transmittance even under cyclic stretching and bending. The films demonstrate excellent conformability to surfaces with random curvatures, making them suitable for THz imaging applications. The wrinkled MXene films offer a promising solution for future smart windows and wearable electronics, addressing the challenges of transparency, flexibility, and high EMI SE.This study presents a novel approach to fabricate stretchable, transparent, and ultra-broadband (0.1–10 THz) terahertz (THz) shielding MXene (Ti₃C₂Tx) films using a wrinkled structure engineering strategy.
