Abstract

CNTs/Ti₃C₂Tx hybrids are prepared with carbon nanotubes (CNTs) are in-situ grown on the surface of the Ti₃C₂Tx nanosheets by using the method of chemical vapor deposition. Internal effects between micro-morphology and interface polarization have been research. The results show that the dielectric properties of the CNTs/Ti₃C₂Tx hybrids increase with the increase of the length of CNTs, the growth time is a direct determinant of the length of CNTs. The factors of the micro capacitors formed by CNTs, the dipoles formed by defects on CNTs greatly increase the dielectric loss. When the growth time reaches 45 min and the thickness of the absorber is 2.0 mm, the minimum reflection coefficient is −60.9 dB in X-band, the absorption bandwidth reaches 2.9 GHz. The CNTs/Ti₃C₂Tx hybrid shows excellent electromagnetic wave absorption properties.
