Graphene film shows excellent performance on not only electric and thermal conductivity, but also mechanical strength, which brought it to be a hot research topic in the last few years. In our study, a free-standing graphene films were prepared from concentrated graphene oxide aqueous solution through solution casting processï¼which gives out excellent mechanical and electrical performance.
Firstly, the graphene oxide aqueous dispersion was prepared and evenly coated on the glass substrate. Then the solidification and drying process were applied to form graphene films, following with various ionic compounds treatments. In our study, we investigated various additives, which can form various chemical bindings to enhance the film surface morphology, mechanical strength, and electric performance, which presented a great potential for industrial application.
