<abstract xmlns="http://www.w3.org/1999/xhtml">In this study a graphene-like material was synthesized by chemical exfoliation of sieved graphite powder with an average particles size ≤100 µm in dispersing medium from tri-, di- and monochloroacetic acid sulfonated with 55 % H2SO3. The results indicated that the yield of graphene-like material was the best in case of trichloroacetic 55 % H2SO3, taking into account structure quality and amount of obtained material. Layered graphene-like material was carefully collected after reduction of GO formed by 50 % dimethylhydrazine. AFM-investigations were performed to characterize nanostructural features of produced graphene and expected surface area which is surface topology dependent. Furthermore, Raman spectra were measured to confirm graphene formation.</abstract>
