Rheological properties and fracture toughness of epoxy resin/multi-walled carbon nanotube composites

Multi-walled carbon nanotubes (MWCNTs), surface-treated via chemical functionalization, i.e., oxidation and amidation, were used to reinforce diglycidylether of bisphenol F (DGEBF) epoxy resin. The effects of the functionalization on the dispersion stability, rheological properties, and fracture toughness of DGEBF/MWCNT composites were investigated. The dispersion homogeneity of the MWCNTs in the epoxy matrix improved after functionalization. In...
