The influence of carbon nanotubes on various chemical reactions has been examined. These reactions include epoxy crosslinking, in situ polymerization of copolymers in the presence of carbon nanotubes and thermal degradation of a thermoplastic matrix. The various characterizations were based on different types of analyses, including differential scanning calorimetry, proton nuclear magnetic resonance, size exclusion chromatography and thermogravimetric analysis. In each case, we show that the presence of multi-walled carbon nanotubes accelerates the process. © 2012 Society of Chemical Industry Multi-walled carbon nanotubes can accelerate various chemical reactions: epoxy crosslinking, in situ polymerization of copolymers and thermal degradation of a thermoplastic matrix.
