Rheo-kinetics was used to observe time-dependent rheological changes in elastic (G?) and viscous (G?) moduli, and complex viscosities of epoxy-CNT samples during isothermal curing. DSC measurements were also performed to monitor the curing reaction, in order to compare against the rheo-kinetic parameters. The Kamal-Sourour kinetic model describes the curing of the epoxy-CNT system for rheo-kinetics and DSC well. The activation energies of the curing reaction were found to be ?36 kJ/mol and ?33 kJ/mol using rheo-kinetics analysis and DSC, respectively. In addition, radio-frequency (RF) electromagnetic fields were used to heat and cure the epoxy-CNT sample; such heating techniques are valuable in a number of epoxy processing technologies. G?, G?, and complex viscosities of RF heated samples were measured to monitor RF-aided curing. This allows us to monitor the curing kinetics inside samples being heated by RF fields; the data indicate that RF-aiding curing is faster than curing rates for samples undergoing curing inside a measurement device such as a rheometer or DSC, because the heat generated is immediate and volumetric.eninfo:eu-repo/semantics/closedAccessCuring KineticsDSCEpoxy-CNTRadio Frequency HeatingRheologyArticle10.1016/j.carbon.2020.12.0901751102-s2.0-85098958170Q1WOS:000626964000001Q1
