Epoxy-PEI interpenetrating polymer network enhanced with electric field-oriented carbon nanoparticles

This research project aims to investigate for the first time the electric field alignment of carbon nanoparticles in an epoxy-poly(ether imide) polymeric system, to enhance electrical conductivity in targeted directions. By applying and tuning an external electric field, the carbon nanoparticles are expected to rotate, create an interconnected network, and promote anisotropic electrical and thermal conduction. By exploring the polymer blend interfaces for the selective localization of nanoparticles combined with electric field alignment, the study aims to obtain a PEI/epoxy nanocomposite with high electrical conductivity at an ultra-low nanoparticle concentration while allowing for a tunable conduction pathway. The extent of alignment and its effects on the nanocomposite properties will be experimentally assessed using techniques such as rheology, microscopy, and dielectric measurements.
