The struc ture of carbon materials was characterized by electron microscopy and adsorption structural analysis by low temperature 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.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлены результаты исследования неоргано-полимерных нанокомпозитов Nafion/терморасширенный графит и Nafion/углеродная сажа методами ядерного магнитного резонанса и термогравиметрии. Структура углеродных материалов охарактеризована с помощью электронной микроскопии и адсорбционного структурного анализа методом низкотемпературной адсорбции азота. Показано наличие взаимодействия полимера Nafion и углеродного материала на границе контакта компонентов, приводящего к термостабилизации композитов, обсуждаются различия между терморасширенным графитом и сажей, обусловленные их морфологией при взаимодействии с Nafion.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стабильность композита</kwd><kwd>миграция Nafion</kwd><kwd>графен</kwd><kwd>углеродная сажа</kwd><kwd>ЯМР</kwd><kwd>термогравиметрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composite stability</kwd><kwd>Nafion migration</kwd><kwd>graphene</kwd><kwd>carbon black</kwd><kwd>NMR</kwd><kwd>thermogravimetry</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>The work was supported by the grant from the Russian Science Foundation No. 22 23-20127, https://rscf.ru/project/en/22-23-20127/ and the grant from the St. Petersburg Science Foundation in  accordance with the agreement of 14.04.2022 No. 28/2022.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Tellez-Cruz M.M., Escorihuela J., Solorza-Feria O., Compa˜n V.
