METHOD OF MANUFACTURING COMPOSITE POLYMER MEMBRANES

摘要

FIELD: membrane technics. SUBSTANCE: polymer substrate is stretched together with selective coating in wetting liquid media giving rise to coating swelling exceeding 5 wt % but not causing dissolution resulting in destroying continuity of coating. Manufactured membrane may find use in separating and concentrating gases, vapors, and liquids in chemical industry, biotechnology, and medicine. EFFECT: facilitated procedure.
