Abstract

Self-aligned in-situ reduced graphene oxide (rGO)/waterborne epoxy (EP) nanocomposite were prepared using an all aqueous method. The nanocomposites delivered a very low percolation threshold of 0.26 wt% as a result of the fine dispersion of monolayer rGO sheets and their ultralarge size. The rGO/EP nanocomposites exhibited exceptionally high dielectric constant arising from the charge accumulation at the highly conductive filler/insulating polymer interface according to Maxwell-Wagner-Sillars polarization principle. The highly dielectric rGO/EP nanocomposites can function as effective electromagnetic interference shielding materials.
