Классические дезинфицирующие средства в виде концентрированных растворов или растворимых таблеток не в полной мере могут удовлетворить потребности при проведении мероприятий по антимикробной протекции поверхностей ввиду необходимости их регулярного повторения, что приводит к большому расходу средств, которые за последние два года подорожали на 30–50%. Поэтому для удешевления процедуры дезинфекции и увеличения ее эффективности предложен подход по созданию средств с пролонгированным действием путем формирования пленкообразующих антимикробных компонентов с хорошими адгезионными свойствами к различным поверхностям. Кроме того, такие системы могут найти применение в качестве добавок к лакокрасочным покрытиям на основе водных эмульсий на этапе косметического ремонта лечебнопрофилактических учреждений. Такие материалы могут значительно замедлить скорость распространения вредоносной микрофлоры, а также обеспечить длительную защиту от нее. Для реализации такого подхода был разработан состав полимер-полимерной смеси на основе поливинилового спирта и полигексаметиленгуанидин гидрохлорида. Следует отметить, что гуанидинсодержащие полимеры проявляют высокую антимикробную активность и низкую токсичность по отношению к человеку, также они широко используются в качестве активных агентов дезинфицирующих средств. Поливиниловый спирт является отличным пленкообразующим полимером и обладает хорошими адгезионными свойствами, нетоксичен и химически инертен. Таким образом, применение таких добавок может существенно снизить распространение вредоносной микрофлоры, особенно на объектах с повышенной социальной нагрузкой.</p></abstract><trans-abstract xml:lang="en"><p>Since 2020, surface disinfection has become particularly relevant thus requiring improved approaches to its implementation. Conventional disinfectants comprising concentrated solutions or soluble tablets fail to fully comply with the need for antimicrobial protection of surfaces, calling for their repetitive application. This leads to considerable expenses, with the price of disinfectants rising by 30–50% over the past two years. In this article, agents characterised by prolonged action due to film-forming antimicrobial components having good adhesion to various surfaces are developed in order to reduce the cost of the disinfection procedure and increase its efficiency. In addition, such systems can be used as additives to water paint coatings for minor maintenance of medical and preventive institutions. These materials can significantly reduce the growth rate of the harmful bacteria population, as well as provide long-term protection against it. In order to implement this approach, the polymer-polymer composition based on polyvinyl alcohol and polyhexamethylene guanidine hydrochloride was developed. It should be noted that guanidine-containing polymers are characterised by high antimicrobial activity and low human toxicity, being also widely used as active agents in disinfectants. An excellent film-forming polymer exhibiting good adhesive properties, polyvinyl alcohol is non-toxic and chemically inert. Thus, the use of such additives can significantly reduce the extension of harmful bacteria, especially in crowded public areas.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полигексаметиленгуанидин гидрохлорид</kwd><kwd>поливиниловый спирт</kwd><kwd>антимикробная активность</kwd><kwd>пленки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyhexamethylene guanidine hydrochloride</kwd><kwd>polyvinyl alcohol</kwd><kwd>antimicrobial activity</kwd><kwd>films</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания Байкальского института природопользования Сибирского отделения Российской академии наук № 0273-2021-0007</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of the state task of the Baikal Institute of Nature Management of the Siberian Branch of the Russian Academy of Sciences no. 0273-2021-0007</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">Шкарин В.
