For IR-opaque objects with zero transmission, tuning a material's reflectivity (i.e., metallicity) equals tuning its emissivity and, thus, the radiative heat transfer at thermal equilibrium. This tunability of emissivity forms the basis for developing advanced electrochromic materials like conjugated polymers, which can modulate radiative heat transfer through precise control of their electronic properties. These materials achieve this by tuning their polymer's carrier density ( ) and thereby altering their plasma frequency ( ). In the 𝑛 𝑐 ω 𝑝 conducting state, metallic conjugated polymers typically exhibit a carrier density on the order of , resulting in a plasma frequency within the infrared regime ( ) . This
