요약
Multi-walled carbon nanotubes (MWNT) were grafted with norbornene groups (MWNT-g-Norbornene) and incorporated into dicyclopentadiene (DCPD) to produce a nanocomposite cured by ring-opening metathesis polymerization (ROMP). The functionalization of the MWNT surfaces during the modification procedure was confirmed by means of FT-IR spectroscopy. Tensile test results showed that the toughness of the DCPD/MWNTg-Norbornene nanocomposites was considerably increased by about 220%, compared to that of neat DCPD. The enhanced toughness could be a result of increased dispersion of MWNT-g-Norbornene and increased interfacial adhesion between the functionalized MWNT and DCPD, as revealed by FE-SEM images of the fractured surfaces.
