| description | The disordered assembly and low conductivity of carbon nanotubes are the main problems that limit the application of electromagnetic interference (EMI) shielding. In this work, an ordered lamellar assembly structure of multiwalled carbon nanotube/Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> (MWCNT/Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>) hybrid films was achieved by vacuum-assisted filtration through the hybridization of Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> nanosheets and carbon nanotubes, where carbon nanotubes were tightly sticking on the surface of Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> nanosheets via physical adsorption and hydrogen bonding. Compared with the pure carbon nanotubes films, the hybrid MWCNT/Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> films achieved a significant improvement in conductivity of 452.5 S/cm and EMI shielding effectiveness (SE) of 44.3 dB under 50 wt% Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> with a low thickness (8.6 μm) and orderly lamellar stacking structure, which finally resulted in high specific SE (SSE/t, SE divided by the density and thickness) of 55,603.1 dB∙cm<sup>2</sup>∙g<sup>−1</sup>. |
