Abstract

The utilization of electromagnetic (EM) energy neither is affected by the weather nor produces harmful substances. How to utilize and convert EM energy is of practical concern. Herein, delaminated titanium carbide (D-Ti ₃ C ₂ T _x ) MXene nanosheet (NS) was successfully fabricated by the modified Gogotsi's method. The choice of atomic layer processing allows tailoring of layer distance of Ti ₃ C ₂ T _x so as to improve polarization. High-performance EM wave absorption of D-Ti ₃ C ₂ T _x MXene NS composites was obtained, and their comprehensive performance is the best of all Ti ₃ C ₂ T _x -based composites. Due to the competition between conduction loss and polarization loss, the higher the concentration of D-Ti ₃ C ₂ T _x in composites, the more the conversion of EM energy to thermal energy will be. Based on the mechanism, a prototype of thermoelectric generator is designed, which can convert the EM energy into power energy effectively. This thermoelectric generator will be the energy source for low power electric devices. Our finding will provide new ideas for the utilization of EM energy.
