Спектроскопические исследования показывают, что добавление ЭГ существенно усиливает фотохромные свойства нанокомпозитов, обусловленные фотоиндуцированным переносом электронов от органической матрицы нанокомпозита на молекулы ФВК.</p></abstract><trans-abstract xml:lang="en"><p>   Poly(vinyl alcohol) (PVA)–phosphotungstic acid (PTA) nanocomposite films were produced from aqueous solutions with the addition of ethylene glycol (EG), which is a plasticizer for PVA and contains OH groups capable of being electron donors during the photoreduction of PTA. Spectroscopic studies have shown that the addition of EG significantly enhances the photochromic properties of nanocomposites caused by photoinduced electron transfer from the organic matrix of nanocomposite to PTA molecules.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотохромные материалы</kwd><kwd>нанокомпозит</kwd><kwd>поливиниловый спирт</kwd><kwd>фосфорно-вольфрамовая кислота</kwd><kwd>фотоиндуцированное восстановление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photochromic materials</kwd><kwd>nanocomposites</kwd><kwd>poly(vinyl alcohol)</kwd><kwd>phosphotungstic acid</kwd><kwd>photoinduced reduction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке Белорусского республиканского фонда фундаментальных исследований (грант № Ф23МЭ-033)</funding-statement><funding-statement xml:lang="en">The work was partially supported by the Belarusian Republican Foundation for Basic Research (grant no.
