Herein, we synthesize copolymers using controlled radical polymerization. Then, a microbead-type latent curing agent for epoxy resin is fabricated in an oil-in-water emulsion. Compared to bare imidazole, the fabricated microbeads are able to effectively suppress reactivity due to the simultaneous operation of chemical modification and physical protection effect. In addition, compared to epoxies made with imidazole, flame retardancy is secured by blocking heat and oxygen due to the high char residue. Also, the increase in stiffness of specimen due to the rigid segment results in the improvement of tensile, shear and impact strength. Lastly, as a proof-of-concept application, we incorporate MXene into epoxies to fabricate composite for electromagnetic interference shielding application. This proof-of-concept study demonstrate that MXene successfully endows the developed composites with high electrical conductivity and EMI shielding properties.
