ABSTRACT The poor compatibility between carbon fibers (CF) and resin matrices limits the application of carbon fiber composites. Inspired by mussel adhesion, a TA coating was deposited on the carbon fibers, serving as a reactive platform to successfully introduce polymer‐modified Fe 3 O 4 nanoparticles onto the surface to enhance the surface activity and roughness of the fibers, thereby improving the mechanical properties of the composites. The results show that the MCF/EP composites exhibit superior flexural strength compared to unmodified CF/EP composites. The interlaminar shear strength (ILSS), and electromagnetic interference (EMI) shielding effectiveness (SE) were increased by 69%, 23.4%, and 114%, respectively. This work provides reference for the development of high‐performance, multifunctional carbon fiber composites with potential applications in fields such as aerospace.
