The interfacial strength between carbon nanotubes and a polymer matrix increases dramatically when the carbon‐nanotube surface is chemically modified. As individual nanotubes are pulled from a polymer matrix, a transition from pullout to fracture occurs (see Figure) at a critical nanotube embedded length, with chemically modified nanotubes showing a smaller critical length than unmodified ones.
