We develop a novel strategy to reinforce an epoxy resin using carbon nanotubes (CNTs) as the filler material, in which polybenzimidazole (PBI) was used as the glue to enable an effective adhesion between the epoxy matrix and CNT surfaces. As the PBI strongly interacts with the surfaces of the CNTs and reacts with epoxy matrices to form covalent bonding, the PBI-wrapped CNTs are a promising material to reinforce the mechanical toughness of epoxy-CNT composites.
