Представлен обзор основных результатов актуальных работ по методам функционализации углеродных нанотрубок и графена, изменению их свойств в результате допирования и возможному применению материалов на их основе. Рассмотрены методы ковалентного присоединения функциональных групп к графену и углеродным нанотрубкам, гетероатомного замещения и нековалентного включения наночастиц и молекул. Показаны перспективы использования химически модифицированных углеродных наноматериалов в производстве нового поколения электронных устройств, обладающих повышенной механической прочностью, гибкостью и эластичностью.

The paper presents a review of the main results of current works on the functionalization methods for carbon nanotubes and graphene, modification of their properties as a result of doping and possible use of materials based on them. The methods of covalent attachment of functional groups to graphene and carbon nanotubes, heteroatom substitution and noncovalent inclusion of nanoparticles and molecules are considered. The perspectives of the use of chemically modified carbon nanotubes and graphene in production of a new generation of electronic devices with high mechanical strength, flexibility and elasticity are shown.
