Sažetak
Recently, great attention has been put on the development of graphene and graphene-based nanomaterials (e.g. graphene/carbon nanotubes (CNTs), graphene/metal oxides). Graphene definition applies not only to a monolayer of carbon atoms but also to a few-layered and multi- layered graphene materials. Even though graphene monolayers provide the highest performance in various applications, they are very expensive and quite difficult to work with because of their tendency to agglomerate in dry form and suspensions. Thus, multilayered graphene provides a better effect-to-cost ratio in most applications. Wider application of such materials requires the development of an effective, inexpensive, and scalable process for their production, and the development of one such method was the focus within this work. Specifically, the purpose of this work was to explore the possibility of obtaining multi- layered graphene materials from expanded graphite formed by thermal expansion of graphite intercalated with a solution of ammonium persulfate in sulfuric acid (GIC), followed by ultrasonic exfoliation of expanded graphite intercalation compounds (EGIC) in the solution of sodium lauryl sulfate. The obtained materials were characterized by SEM, FTIR, and TGA techniques, and compared with the commercial graphene A12 (Graphene Laboratories).
