Researches on the Production of Conductive Aluminium-Graphene Composites

All over the world, intensive research is being conducted on the development of new conductive materials to be used in power engineering. The objective of this research is to increase electrical conductivity in wire and cable materials, and consequently, to increase line current-carrying capacities and reduce losses in electric energy transfer. Today, the expectations in the power engineering sector concentrates on conductive materials with electrical conductivity higher than conductivity of base materials, i.e. aluminum. The scientific discovery of the recent years, graphene, one of carbon allotropic variants with a very high electrical and thermal conductivity and mechanical strength, creates great possibilities to design and manufacture new materials, with super-standard functional properties. Graphene, can be a new kind of “alloy additive” to aluminum, which can significantly change their electric and another properties.This article focuses attention on the possibilities of graphene and aluminum synthesis. The researches was made over the different methods of producing these materials, in particular: chemical synthesis consisting in the combination of liquid metal with graphene into a form suitable for further processing in the processes of forming into wires. The article presents the results of mechanical properties and structural studies of aluminum-graphene composites.
