Abstract

Изобретение относится к композиционным материалам, а более конкретно, к композиционным мембранным материалам на основе полимерных материалов, используемых для очистки жидкости, в частности, питьевой воды. Новый композиционный материал для фильтрационной очистки жидкости выполнен из полимерной мембраны, представляющей из себя фибриллярно-пористую матрицу, содержащую гидрофильный полимер и металлический антибактериальный агент. Фибриллярно-пористая матрица содержит, по меньшей мере, в части своего объёма устойчивые активные зоны, состоящие из кластеров металлического антибактериального агента в комбинации с молекулами гидрофильного полимера, при этом, по меньшей мере, часть кластеров металлического антибактериального агент связана друг с другом и с поверхностью пор матрицы молекулами гидрофильного полимера, причём, по меньшей мере, часть кластеров металлического антибактериального агента дополнительно химически связана с поверхностью пор матрицы, где среднее расстояние между активными зонами меньше, чем по меньшей мере трёхкратный средний диаметр пор матрицы. Техническим результатом, достигаемым при использовании изобретения является достижение устойчивой гидрофильности полимерной мембраны в процесее её эксплуатации при одновременном сохранении проницаемости полимерной мембраны и повышении бактериостатичности композиционного материала. Дополнительным техническим результатом, достигаемым при использовании изобретения, является повышение бактериостатичности околомембранного пространства в процессе фильтрации жидкости.
