The development of infrared-radar compatible materials/devices is challenging because the requirements of material properties between infrared and radar stealth are contradictory. Herein, a composite of poly(3, 4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) coated melamine foam is designed to integrate the advantages of the dual materials and the created heterogeneous interface between them. The as-designed PEDOT:PSS@melamine composite shows excellent mechanical properties, outstanding thermal insulation, and improved thermal infrared stealth performance. The relevant superb radar stealth performance including the minimum reflection loss value of -57.57 dB, the optimum ultra-wide bandwidth of 10.52 GHz, and the simulation of radar cross section reduction value of 17.68 dB m , can be achieved. The optimal specific electromagnetic wave absorption performance can reach up as high as 3263.02 dB·cm g . The average electromagnetic interference shielding effectiveness value can be 30.80 dB. This study provides an approach for the design of high-performance stealth materials with infrared-radar compatibility.
红外-雷达兼容材料/器件的发展具有挑战性，因为材料性能在红外和雷达隐身方面的要求是相互矛盾的。在此，设计了一种聚（3,4-亚乙基二氧噻吩）：聚苯乙烯磺酸盐（PEDOT：PSS）涂覆三聚氰胺泡沫的复合材料，以整合两种材料的优势及其之间形成的不均匀界面。所设计的 PEDOT：PSS@三聚氰胺复合材料具有优异的机械性能、出色的隔热性能和改进的热红外隐身性能。相关的卓越雷达隐身性能包括最小反射损耗值为-57.57 dB、最宽的超宽带为 10.52 GHz 以及雷达散射截面减少值为 17.68 dB m 的模拟值，均可以实现。最佳的特定电磁波吸收性能可高达 3263.02 dB·cm g。平均电磁干扰屏蔽效能值可达 30.80 dB。本研究为设计具有红外-雷达兼容性的高性能隐身材料提供了一种方法。
