MXene has attracted extensive attention in the fields of electrochemical energy storage and conversion, photothermal conversion, and electromagnetic shielding due to its unique two-dimensional structure. This study creates an infrared electrochromic device based on Ti3C2Tx MXene and achieves dynamic thermal radiation regulation.
Due to its unique two-dimensional structure, MXene has attracted extensive attention in the fields of electrochemical energy storage and conversion, photothermal conversion, and electromagnetic shielding. With the capacitive and photoelectric properties combined, an infrared electrochromic device based on Ti3C2Tx MXene is created and employed for dynamic thermal radiation regulation. The device exhibits dynamic emissivity variations of 0.31, 0.24, and 0.23 in the wavelength bands of 3-5 mu m, 8-14 mu m, and 2.5-18 mu m, respectively. However, the regulation mechanism of MXene's infrared emissivity is not clear. In this work, the morphology, structures, and electrochemical properties of MXene were characterized and analyzed. The results reveal that the reason for MXene's emissivity variation is related to the changes in the free O-terminal groups caused by Li-ion intercalation/deintercalation. This paper creates a new application of MXene in the field of dynamic regulation of thermal radiation.
