Direct‐Ink‐Writing Printed Aerogels with Dynamically Reversible Thermal Management and Tunable Electromagnetic Interference Shielding

, and 60% compressive strain, the aerogel achieves an optimal shielding effectiveness of 80 dB. Additionally, the aerogel exhibits reversible infrared stealth and dynamically switchable thermal properties (from 0.08 to 0.67 W·m⁻¹·K⁻¹) in response to environmental humidity variations. This work demonstrates a versatile approach for structurally adaptive EMI shielding materials with self-regulating thermal behavior, offering promising applications in harsh environment protection, intelligent thermal camouflage, and adaptive shielding for next-generation aerospace and communication technologies.
