This contribution contains data on thermal stability of certain materials whose initial precursor is graphite. Graphite was oxidized separately and in a mixture with fullerene C60. The prepared oxides were processed with vacuum filtration to produce foils and their morphology and thermal stability was described. The graphene oxides reacted with nano-cellulose and ß- glucan to produce composites. The prepared composites in the form of foils were tested for thermal stability and further analyzed e.g.by FT-IR, SEM, etc.
