Results of DSC scans at 10 °C/min, for the neat epoxy resin and epoxy resins with 3 wt % of different carbon nanofillers: enthalpy changes, normalized with respect to the resin weight (∆HU), peak temperature (Tpeak), and fraction of catalyzed reaction.

| Epoxy + oCB-2 (O/C = 0.83) | 383.8 ± 1.1 | 96.2 ± 0.7 | 34 |
| Epoxy + oCB-3 (O/C = 0.91) | 352.5 ± 1.7 | 88.7 ± 1.1 | 56 |
| Epoxy + eGO (O/C = 0.62) | 374.4 ± 2.3 | 95.0 ± 0.7 | 29 |
