СПОСОБ ПОЛУЧЕНИЯ АСИММЕТРИЧНОЙ ТРЕКОВОЙ МЕМБРАНЫ

摘要

FIELD: methods of manufacture of asymmetric polymer membranes with thin selective layer containing pores of micro- and nano-metric ranges. SUBSTANCE: proposed method includes radiation of polymer film with heavy charged particles followed by chemical pickling at additional treatment of film by action of ultra-violet radiation or plasma in oxygen-containing atmosphere on one side or by beam of charged particles; chemical pickling is performed in solution containing at least two dissolved components: pickling agent and surfactant. EFFECT: increased productivity due to continuous technological process. 7 cl, 7 dwg
