Abstract
AbstractRecently, the interfacial bonding between nanodiamonds (DNDs) and multi‐walled carbon nanotubes (MWCNTs) in epoxy‐based nanocomposites were found. In this work, effects of amino functionalization on MWCNTs and DNDs introduction on rheology, dynamic mechanical properties, and thermal stability of MWCNTs epoxy‐based nanocomposites are discussed. The results show that pristine MWCNTs increase the complex viscosity, lower the molecular weight of epoxy net chains as well as glass transition temperature (Tg), and expand the phase separation. Amino functionalization of MWCNTs make the behaviors above disappeared nearly. Besides, introduction DNDs improved Tg and restricted the phase separation as well, but the high complex viscosity and non‐Newtonian behavior remains. This work may provide inspirations for the further researches about hybrid fillers.
