description | Kinetic peculiarities of polycyclotrimerization process of dicyanate ester of bisphenol A (DCBA) in the presence of multi-walled carbon nanotubes (MWCNTs) have been investigated using Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy technique. It has been found that even very small amounts of MWCNTs (0.01–0.1 wt%) catalyze the reaction of polycyclotrimerization of DCBA leading to formation of polycyanurate network (PCN)/MWCNTs nanocomposite. However, some decrease in final degree of conversion for nanocomposites compared to the neat PCN within the temperature/time schedule used was observed. The kinetic rate constants increased with addition of MWCNTs and energies of activation were found to be significantly decreased even at low contents of MWCNTs. |
