4. Conclusions
- A new CNTs/Mg matrix laminated composite was prepared by ARB method, which was applied to the field of electromagnetic shielding.
- When the EPD time was 8 min, in the testing frequency of 8.2–12.4 GHz, the SE value was 85–96 dB. The main shielding mechanism was closely related to the layered structure. Since the impedance of adjacent layers was inconsistent, the layered structure increased the multilayer reflection ability.
- Oxide layers and other contaminants could be introduced into the interlayer during EPD and ARB process. Due to the existence of CNTs, the electrical conductivity declined slightly, and the value was 22.07, 21.96 and 21.89 × 106 S/m, respectively.
