Role of Interphase Region on Electrical Conductivity of Polymer Nanocomposites

This paper aims to investigate the effects of the interphase region on the electrical conductivity properties of epoxygraphene coatings. Various factors such as aspect ratio of graphene, volume fraction of graphene, filler orientation angle, and interphase thickness impact the conductivity properties of these coatings. Of all these contributingfactors, the thickness of the interphase region is one of the key components in achieving interconnected conduction networks. In addition, since the thickness of this region can be changed by adjusting the degree of oxidation of graphene, in this project, by changing the level of surface oxidation of graphene, the thickness of the interphase region was changed and the effect of this region on the conductivity properties was investigated.
