Application with graphene as the functioning element is commonly achieved through the creation of interconnected graphene-graphene networks. The so-called Langmuir-Blodgett self-assembly has been the cornerstones for building up the graphene-graphene networks starting commonly with graphene oxide (GO) as precursors. For example, methods based on the self-assembly of GO were capable of producing single- or few-layered graphene-graphene networks [1, 2]; the graphene-graphene networks with such thickness were transparent yet electrically conductive.
