Influence of hybrid carbon nanofillers on the cure behavior and properties of epoxy material

Abstract

The curing process of epoxy compositions with 1-butylimidazole (2 phr as a catalyst) and hybrid carbon nanofillers: multiwalled carbon nanotubes (CNTs) and graphene (GN) (total carbon nanofillers content 0.25—1.0 wt %) has been characterized via rheometry. Thermomechanical measurements of epoxy composites revealed a rather large decrease in the glass transition temperatures depending on CNT/GN weight ratio and total nanofillers content. Electrical volume resistivity of epoxy materials decreased about 8—10 orders of magnitude after modification with 0.25—0.50 wt % CNT/GN hybrids to the range 105—106 Ω•m.
