Получены новые полимерные медьсодержащие нанокомпозиты на основе поли-N-винилимидазола. Формирование нанокомпозитов осуществляли методом химического восстановления ионов меди из раствора ацетата меди аскорбиновой кислотой в водной среде в присутствии полимера. Нанокомпозиты получали при молярном соотношении полимер:Cu(II) 10:1 и 5:1. В результате реакции восстановления были получены нанокомпозиты в виде порошков красно-коричневого цвета с металлическим блеском. Установлено, что содержание меди в полученных нанокомпозитах зависит от исходного молярного соотношения стабилизирующего поли-N-винилимидазола и Cu(II) и составляет 5,9 и 11,7%. Образование наноразмерных частиц меди исследовано и подтверждено методом УФ-спектроскопии. В оптических спектрах водных растворов медьсодержащих нанокомпозитов наблюдаются максимумы при 537–541 и 646–651 нм, что подтверждает образование ультрадисперсной меди в наноразмерном состоянии. Полученные медьсодержащие нанокомпозиты на основе поли-N-винилимидазола являются перспективными в медицине, катализе, для применения в оптических, сенсорных и электронных устройствах.

New polymer copper-containing nanocomposites based on poly-N-vinylimidazole were obtained. The formation of nanocomposites was carried out using the method of chemical reduction of copper ions from a solution of copper acetate with ascorbic acid in an aqueous medium in the presence of a polymer. Nanocomposites were prepared at the polymer:Cu (II) molar ratio of 10:1 and 5:1. The reduction reaction yielded powder nanocomposites of a red-brown colour and having a metallic shine. It was found that the content of copper in the obtained nanocomposites depends on the initial molar ratio of the stabilising poly-N-vinylimidazole and Cu (II), reaching 5.9% and 11.7%. The formation of nanosized copper particles was investigated and confirmed by UV spectroscopy. The optical spectra of aqueous solutions of the obtained copper-containing nanocomposites contained maxima at 537–541 and 646–651 nm, which confirmed the formation of ultradispersed copper in the nanosized state. The obtained copper-containing nanocomposites based on poly-N-vinylimidazole are promising materials for use in medicine and catalysis, as well as in optical, sensor and electronic devices.
