As the 5G era approaches, the number of electronic applications grows exponentially, causing electromagnetic waves to affect human health and the regular operation of devices. Unique one-dimensional CNTs and two-dimensional MXene have high electrical conductivity, making them promising candidates for EMI shielding applications. The electromagnetic interference shielding efficiency (EMI SE) of epoxy composites using carbon nanotubes (CNTs) and MXene hybrid fillers was investigated. When a cationic surfactant is grafted on a CNT, it has a positive charge, and MXene has a functional group on its surface, which indicates a negative charge, so it can be self-assembled by electronic attraction to obtain a hybrid filler. Hybrid fillers exhibit improved electrical conductivity and EMI SE compared to individual fillers. The EMI SE and morphology of hybrid fillers were studied in various weight ratios.
