A low viscosity epoxy resin (EPON 815 C) with an aliphatic curing agent (EPIKURE 3282) was used in this study. The lower viscosity of EPON 815C (10 poise) compared to EPON 828 (300 poise), which we used in an earlier study [36], made it easier for the CNTs to align in the direction of the applied magnetic field. The resin/curing agent system cures at room temperature compared to 120 °C for the EPON 828, which uses an aromatic curing agent. Since no heating is involved in curing, a loss of CNT orientation due to a drop in viscosity was eliminated.
