Abstract Scope |
Recent computational and experimental studies on copper/graphene nanocomposites indicate the potential for graphene additions to improve upon the conductive properties of polycrystalline copper. In order to ascertain the effect of these additions and disambiguate their contribution with respect to microstructure on their ultimate conductivity, we have developed a finite difference-based calculation of electrical conductivity as a function of microstructure. To this end, the effects of grain size, texture, dislocation density, and graphene content on the conductivity of the Cu-Graphene nanocomposites were evaluated. Additionally, a parameter study was performed to evaluate the effect of graphene on the Cu grain boundaries on the associated change in grain boundary conductivity. Our calculations indicate a range of grain size, grain boundary coverage, and change in grain boundary properties that would likely result in an improvement upon bulk Cu conductivity. |
