Synergistic effect of functionalized graphene oxide and carbon nanotube hybrids on mechanical properties of epoxy composites.

Epoxy resin was grafted to graphene oxide (GO) esterification reaction and 3D structure hybrids were prepared by combining 1D carbon nanotube (CNT) and 2D functionalized GO through π-stacking interaction. Epoxy composites filled with 3D structure hybrids were fabricated. The results show that functionalized GO effectively improves the dispersibility of CNTs in epoxy matrix due to good compatibility.
