Epoxy resins are an important class of polymers used in different engineered applications. The introduction of carbon fillers can confer them smart functions such as self-sensing propertie, heating ability, auto-repair function, etc. The influence of functionalized carbon nanotubes on the curing kinetics of epoxy resin has been studied by dynamic Differential Scanning Calorimetry (DSC). The activation energy was computed using an advanced iso-conversional method. The inclusion in the resin of functionalized nanofillers lead to a reduction of activation energy for > 0.7, a value of conversion for which it is considered that the reaction of secondary amines is active.
