Experimental study demonstrates superior thermal insulation and leakage-free temperature regulation in dual-skeleton composite aerogels, highlighting their high potential for infrared stealth.

Key Points

To develop a leak-free composite aerogel with dual solid skeletons that integrates solid–solid phase transitions and nanoporous structures for advanced infrared stealth.
Synthesized dual-skeleton composite aerogels through homogeneous mixing of phase change materials with polyimide networks.
Characterized material density, nanoporous architecture, thermal conductivity, and cyclic durability against pure polyimide aerogels.
Assessed thermal shielding and infrared stealth by measuring surface radiation temperatures over a heated graphite substrate.
The composite aerogel exhibited lower density, more intricate pore structures, and reduced thermal conductivity compared to pure polyimide aerogels.
The material retained a maximum phase transition enthalpy of 111 J g⁻¹ with zero phase-change material leakage across thermal cycles.
Application over a 136 °C graphite surface reduced the detected surface infrared radiation temperature to 25.5 °C.
