Abstract：Dynamic infraredcontrol technologyhasgreatapplication value inthe fieldof intellgent thermal managementand adaptivecamouflage，but itsdevelopment faces thekey botteneck of traditional electrochromic devices. Mainstream electrochromic devices such as metal oxidesand conductive polymers generally have problems such as strong dependenceontheconductive layer and high interface impedance.The new infrared control devices basedon carbon nanomaterialsare limited bythecomplex preparation processand therisk of electrolyte leakage，whichrestricts their practicalapplication.Toadress thesechallenges，thisstudy proposed asynergisticconstructionstrategyof single-walled carbon nanotube electrode prepared by spraying method and hot-presed polyurethane solid electrolyte，and successfully developedaflexible solid-state infrared control device integrating functional layerand conductive layer. Experimental results demonstrate that the optimized device achieves a high emissvity modulation amplitudeof 0.52 in the 8-14μm wavelength range，along with a rapid second-level switching speed. After 4OO cycles，the device maintains 86.3% of its initial modulation performance.Even after 2Oo mechanical bending cycles，it retains 94.6% of its original performance，highlighting excelentcycling stabilityand mechanical flexibility.This study providesanew idea for the development of flexible infrared control devices with high integration and bending resistance.
