Abstract

I will introduce our research progress in using polyaniline for mid-IR emissivity tuning and comparative study of the ordinary planar device versus metasurface design. Polyaniline has the suitable and tunable plasmon frequency to work as a dynamic mid-IR material. The metal-insulator transition driven by electrochemical reaction is significant and non-volatile, ideal for long-term wearable thermoregulation. The metamaterial approach is based on metal-insulator-metal perfect absorber configuration, with rational material design to enable electrochemical dynamic switching of absorptivity/emissivity. I will also share our characterization of polyaniline’s mid-IR electrochromic properties and refractive index, hoping to enrich the material palette for the tunable mid-IR photonics research community.
