Manipulating optical properties of MXene/TiN with strong nonmetallic plasmonic coupling for multifunctional imaging attenuation
Plasmonic materials enable flexible optical manipulation owing to their unique plasmon resonance, making them highly promising for photoelectronic imaging attenuation. However, designing plasmonic materials capable of multifaceted imaging attenuation remains challenging. This study theoretically designed and experimentally prepared a unique dual nonmetallic plasmonic Ti3C2Tx/TiN hybrid. The composite material exhibited excellent performance in multifrequency, active/passive, and polarized multifunctional imaging attenuation. TiN nanoclusters were chemically bonded to Ti3C2Tx nanosheets through an ultrasonic-assisted method to form a Ti3C2Tx/TiN hybrid. The strong nonmetallic plasmonic coupling within these hybrids enables superior absorption and excellent photothermal conversion. Consequently, MXene/TiN aerosols demonstrated an improvement of approximately 14% in imaging attenuation compared with traditional oil–water aerosols in visible-light imaging. In addition, the hybrid exhibited strong electromagnetic wave absorption, covering nearly the entire 8.96–18 GHz range. Moreover, polarization imaging attenuation improved by 8.3% compared with that of oil–water aerosols, as evidenced by algorithmically dehazed images. Furthermore, the material effectively provided “high-temperature thermal concealment” for far-infrared active imaging attenuation. This study paves the way for developing multifunctional imaging attenuation materials, with significant potential for future imaging attenuation technologies.
