摘要: Abstract Here we report the effect of multi-walled carbon nanotubes (MWCNTs) and thermally reduced graphene (TRG) on miscibility, morphology final properties nanostructured epoxy resin with an amphiphilic poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymer. The addition nanoparticles did not have any influence miscibility PEO-PPO-PEO copolymer in resin. However, MWCNTs TRG degree crystallinity PEO-rich microphases blends above 10 wt.% while they change phase at nanoscale, where PPO spherical domains 20–30 nm were found all samples studied. A synergic between self-assembled nanostructure toughness cured was observed. In addition, minimized negative elastic modulus glass transition temperature
