Abstract

Epoxy resin/polyetherimide/graphene nanoplates (EP/PEI/GnPs) composites were prepared by solution blending, and the effects of GnPs on the phase structure and electrical properties of the systems were investigated by scanning electron microscopy (SEM), optical microscopy (OM), digital ultrahigh resistance and microcurrent measuring meter and precision impedance analyzer. The results show that the phase separation morphology of the composites change from sea-island structure to bicontinuous structure and phase inversion structure with the increase of GnPs content. The composites have an electrical percolation threshold of 0.85 wt%. A high dielectric constant of more than 310 at 1 kHz could be obtained for the composite with a filler content of 1.75 wt%.
