Multi-scale interphase construction of self-assembly naphthalenediimide/multi-wall carbon nanotube and enhanced interfacial properties of high-modulus carbon fiber composites

Amino terminated and π-conjugate naphthalenediimide (NDI) was designed and novel interphase with self-assembled NDI/multi-wall carbon nanotube (MWNT) was constructed on high-modulus carbon fiber (HMCF) surface, and the interfacial properties and reinforcing mechanisms of HMCF composites with various interphase were investigated. The nanoscale stiffening interphase with intertwined MWNT and flat ensiform nanostructure from NDI self-assembly were...
