| Abstract Scope |
Nanomaterials such as graphene enhance electrical properties of matrix materials they have been embedded in by providing high velocity pathways for electrons and phonons. Recent literature shows that the electrical conductivity of highly conductive metals such as copper and aluminum is further improved with the addition of small concentration of graphene using solid phase processing approaches. This talk explores the effect of additive dimensionality (2D vs. 3D) and size on the electrical properties as a function of temperature. Experimental and modeling results show that as the number of layers in a graphene additive flake increase, its efficacy to enhance electrical performance of a metal matrix decreases, necessitating larger additive concentrations. However, graphene with higher number of layers also shows improved electrical performance at elevated temperatures suggesting a semi-conductor like performance. Such metal composites with elevated electrical performance are crucial for applications as next generation conductors in grid, transportation, and electronics. |
