Since every object above absolute zero inevitably radiates infrared energy, infrared imaging poses a significant threat to important targets. And the advancement of infrared detection technologies in recent years necessitates the development of novel stealth materials that can actively manipulate thermal signatures.
Here, we report a Ti 3 C 2 T x /Bi 2 Se 3 hybrid designed with high-efficiency photothermal conversion for an active infrared thermal stealth strategy. Bi 2 Se 3 was prepared using bismuth on Se nanodisks grown via Cu 2+ -induced strategy, and Ti 3 C 2 T x MXene and Bi 2 Se 3 were then successfully composited through a facile ultrasonic process. Owing to Efficient light absorption and charge transfer between Ti 3 C 2 T x MXene and Bi 2 Se 3 , the hybrid exhibited a remarkable photothermal conversion efficiency of approximately 52.03%. In the simulated infrared detection, the Ti 3 C 2 T x /Bi 2 Se 3 can gradually conceal the real bear target model in the environmental within 10 minutes through photothermal conversion.
This work constructed a Ti 3 C 2 T x /Bi 2 Se 3 hybrid to explore a thermal protection strategy in infrared imaging via its enhanced photothermal conversion, providing a promising strategy for developing advanced photothermal materials in stealth technologies. The work entitled “ Efficient photothermal conversion in a Ti 3 C 2 T x /Bi 2 Se 3 hybrid for infrared stealth ” was published on Energy Materials (published on Apr. 14, 2026).
