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.
