Abstract
In this work, we propose a chemorheological study of an epoxy resin cured with carboxy-double-walled carbon nanotubes (C-DWNTs) reacted with N-methyldiethanolamine (MDEA). The results showed that 1 wt.% C-DWNTs speed up the cure process of more than 40 min. The NMR analysis suggests that a possible explanation of these findings is due to the interaction between the carboxylic functionalities of the DWNTs with the MDEA amine groups creating the –NHCO groups. Finally, an excellent agreement between the chemorheological model and the experimental data was found.
