In this work, we introduce solution-processable CP as the actively tunable material to the application in broadband variable thermoregulation metasurfaces. We synthesize tunable polyaniline (PANI) doped with camphor sulfonic acid (CSA), featuring its high stability, superior optical conductivity for intrinsic IR reflection, and scalable room-temperature polymerization process. The complex permittivities at its lossy dielectric and metallic state on the opposite side of Anderson-Mott transition were characterized through IR spectroscopic ellipsometry. Finally, we performed design and optimization and demonstrated the potential of incorporating CPs for wide angle dynamic metasurface emitter application.
