EMI Shielding Performance and Mechanical Properties of Proton Acid Treated Ti3C2Tx MXene/CNT Composite

After the colloidal proton acid treatment, the preparation of titanium carbide Ti3C2Tx was achieved. In addition, the singlewalled carbon nanotube (SWCNT) was used as reinforcement to improve the mechanical properties of proton acid treated titanium carbide (H-MXene): the tensile property is enhanced by nearly 400% while the electromagnetic shielding performance is retained. This study demonstrates that the H-MXene and carbon nanotube have great potential in electromagnetic interference (EMI) shielding composite materials with excellent mechanical properties.
