Curing agent acts as a link of epoxy resin molecular chains, its molecular structure will affect the various properties of epoxy resin. In this paper, the influence of curing agent molecular structure on the thermal properties, polarization properties, charge transport properties, and energy storage properties of epoxy films were comprehensively discussed by adjusting the ratio of alicyclic amine to polyether amine in curing agent. The results show that with the increase of proportion of rigid alicyclic amine in curing agent, the thermal stability of epoxy resin is significantly enhanced, and the dielectric loss is greatly reduced. This is mainly because the increase of rigid groups can effectively restrict the turning of molecular segments and the transporting of charge. Meanwhile, with the increase of ratio of alicyclic amine, the electric strength and charge-discharge efficiency of the epoxy film increase at first and then decrease. The F51/AP1.6 has the most excellent electric strength, energy density, and charge-discharge efficiency under four different ratios of curing agent. This is related to its stable molecular structure, low dielectric loss, and extremely high deep traps density.
