The present disclosure relates, according to some embodiments, to compositions and devices operable for infra-red transmission and blocking comprising a layered structure having a first electrically conducting layer, a conjugated electrochromic polymer layer, an electrolyte layer and a second electrically conducting layer, wherein the first and second electrically conducting layers have an infrared transparency and the conjugated electrochromic polymers may be operable to be electrically switched between a transparent state that transmits infrared light to an opaque state that does not transmit infrared light. In some embodiments, a device of the disclosure may also have one or more outer substrates sandwiching the other layers. Some embodiments relate to single-layered devices. Some embodiments relate to combined layers. Compositions and devices of the disclosure may be integrated into a wide variety of infrared systems for transmission, shuttering and calibration applications.
