Abstract

2D MXene significantly enhances the microwave absorption properties of a polymer blend (PVB- PEDOT:PSS or PVBPS). For various military and civilian applications such as X-band (8.2–12.4 GHz) and Ku-band (12.4–18 GHz) absorption these materials are very important. The minimum reflection loss (RL)-53 dB was obtained for optimally prepared PVBPS- Ti₃C₂T_x MXene nanocomposite for thickness of 1.5 mm. A single 2 mm thick layer of PVBPS- Ti₃C₂T_x MXene nanocomposite shows the most promising absorption bandwidth (RL≤-10 dB from 8.2 to 18 GHz). Mechanistically, dielectric loss and interfacial polarization contribute more efficiently, and the stored energy becomes predominant in Ti₃C₂T_x MXene contained PVBPS blend which enhances the microwave absorption bandwidth.
