Investigation of stability of composite Nafion/nanocarbon material

The article presents the results of a study of inorganic-polymer nanocomposites Nafion/thermally expanded graphite and Nafion/carbon black by nuclear magnetic resonance and thermogravimetry. The structure of carbon materials was characterized by electron microscopy and adsorption structural analysis by lowtemperature nitrogen adsorption. The presence of the interaction of Nafion polymer and carbon material at the interface between the components leading to thermal stabilization of the composites is shown, and the differences between thermally expanded graphite and carbon black due to their morphology during interaction with Nafion are discussed.
