In our previous experiments, we grew heterostructure of alternating layers of graphene and clay, now we aim to optimize preparation of sandwich structure of graphene and clay. We use synthetic fluorohectorite clay, which are 1 nm thin negatively charged sheets kept together by interlayer cation, and we exchange them by precursor carbon molecules –dyes. We demonstrated that we can synthetize graphene in clay interlayer using different dyes, such as safranine, cyan violet etc. at very low temperatures (600-750 •C) compared to standard process used in industry (3000 •C). New sandwich heterostructure – 2 layers of clay with heteroatom doped graphene in the interlayer is promising candidate not just for fabrication of doped graphene itself, but also electronic applications. We plan to optimize synthesis and annealing protocols in proposed experiment.
