- Аннотация: Film samples produced by codeposition of salts Na(form), Ni(form)2, Co(Аcac)3, and Pb(Аc)2from graphene oxide dispersions are studied. The thus-prepared materials are characterized by spectral and X-ray analytical methods. The structure of graphene oxide containing salt crystals is studied by scanning electron microscopy (SEM). Crystallization occurs both on the surface and in the interlayer spaces of graphene oxide. No side processes occur during crystallization; the precursor salts retain their phase composition, except for lead acetate, which is partially hydrolyzed in aqueous solution. The incorporation of salt crystals increases film imperfection and enhances the resistivity of the material severalfold. The results of this studycan appear useful in the development of graphene oxide based membranes.
