We propose a novel method to uniformly graft high‐density carbon nanotubes (CNTs) onto carbon fiber (CF) by using coupling agents. Coupling agents can supply much more active groups, which is beneficial for grafting high‐density CNTs onto CF surface. After CNT grafting treatment, there are still substantial amounts of reactive groups, which can further react with various types of molecules to meet different requirements. To create chemical bonding between CF and high‐density polyethylene, CF‐CNT was further grafted get reinforcement. The interfacial adhesion of the resulting composites showed a dramatic improvement.
