EFFECTIVE ELECTRICAL CONDUCTIVITY ESTIMATION FOR A NOVEL MULTI-PHASE COMPOSITE MATERIAL

摘要

The paper aims to present a novel configuration of a mixed conductive particles embedded into a non-conductive polymeric matrix, that we call a multi-phase composite material, developed to exhibit predictable electrical conductivities. Graphite and iron particles, having different volume fractions, were blend together into a PVAc matrix with the aim of sizing the influencing factors on sample's measured electrical conductivities. The retrieved values were plotted against some theoretical models from literature.
