Towards highly electrically conductive and thermally insulating graphene nanocomposites: Al2O3-graphene

Popis výsledku v původním jazyce

Highly electrically conductive materials with low heat transfer rates are of very high importance for high temperature fuel cell technologies and the refractory material industry. We aim to develop such materials with high electrical conductivities/highthermal resistivities by creating composite materials of graphene and Al2O3. Here we describe a novel and facile method for the synthesis of Al2O3-graphene composites. Graphite oxide, which was prepared by the Hofmann method, was reduced by active hydrogen generated by the reaction of aluminum with a solution of sodium hydroxide. This reaction led to the formation of a nanocrystalline composite of graphene and aluminum hydroxide. The Al(OH)3-graphene composite was then calcined and pressed into pellets.Sintering of the pellets yielded a nanostructured Al2O3-graphene composite. We characterized the properties of the Al(OH)3-graphene and Al2O3-graphene composite materials in all steps to get an understanding of the process of the nanocom
