Abstract :

Hyid products were prepared by oxidation of graphene and joint oxidation of graphene and fullerene C60 in various weight ratios, which allowed preparation of foils of diverse morphologies. The prepared initial matrices can be used for further treatment, such as fluorination, omination, embedding of metals with catalyst effects, preparation of composite materials in combination with other polymers or nano fibers, or in form of lamellar fibers by freeze drying. They can be widely used as adsorbing/ absorbing materials with new physicochemical properties (electric, optical etc.) A pilot experiment performed in this work has proved adsorption capacity of the prepared foils in respect to radioactive uranyl nitrate by means of a liquid scintillation spectrometer HIDEX 300 SL which measured total alpha and beta activity of filtrate and spare solution of uranyl nitrate. Adsorption capacity of the foils depended not only on the weight ratio of graphene oxide and fullerene C60 but also on the method of preparation of the foils and on their morphology
