Abstract

See full text

A dynamic thermal infrared stealth composite material based on dual phase change is a VO2/mica-based phase change thermal storage thin layer composite material composed of a VO2 nanoparticle coating and a mica-based phase change thermal storage thin layer, wherein the mica-based phase change thermal storage thin layer consists of stearic acid and a vanadium-extracted mica substrate in a mass ratio of 3-5:5-7. The composite material based on dual phase change is prepared by extracting vanadium from vanadium mica using a roasting and acid leaching process to prepare VO2 nanoparticles and a vanadium-extracted mica, embedding a phase change functional body into the vanadium-extracted mica as a support substrate to prepare a mica-based phase change thermal storage thin layer, and coating the VO2 nanoparticles on the mica-based phase change thermal storage thin layer. The dynamic thermal infrared stealth composite material can synergistically reinforce thermal infrared stealth performance.
