 This paper presents a novel composite material consisting of PEDIT PSS coating on top of melamine foam. The material has excellent mechanical properties, thermal insulation and improved thermal infrared stealth performance. It also demonstrates superior radar stealth performance, with a minimum reflection loss of minus 57.57 dB, an optimum ultra-wide band of 10.52 GHz, and a simulation of radar cross-section reduction of 17.68 dBm2. Additionally, it exhibits an average electromagnetic interference shielding effectiveness of 30.80 dB. This study provides an approach for the design of high performance stealth materials with infrared radar compatibility.
