Polymers also offer tremendous degrees of freedom in terms of fabrication and molecular engineering to tailor to the applications . Considerable research efforts in polymer synthesis, side chain engineering, and post-processing have been made to further expand the plasmonic and electrochromic performance by improving the charge carrier density and mobility . In the longer wavelength range, CPs have long been the popular candidates of mid-infrared (mid-IR) variable emissivity applications. Compared to single-mode heating/cooling devices, CPs offer the possibility to actively tune the emissivity while maintaining it without any energy consumption .
