METHOD OF PRODUCING TRACK MEMBRANE FOR BLOOD FILTRATION Russian patent published in 2014 - IPC B01D67/00 B01D71/06

Abstract RU 2519184 C1

FIELD: chemistry.

SUBSTANCE: method of producing track membrane for blood filtration includes irradiation of polymer film with accelerated charged particles, its sensibilisation by radiation in ultraviolent range and successive processing irradiated film with etching alkaline reagent, solution of polyethyleneimine and solution of polyvinylpyrrolidone. As charged particles used are krypton ions with irradiation density 0.9·10⁹÷1.1·10¹⁰ ion/cm². Exposure time in the process of film sensibilisation by radiation in ultraviolet range constitutes 9-17 minutes with ultraviolet A intensity 5.8-12.5 W/m², and ultraviolet B - 2.6-4.4 B W/m².

EFFECT: invention makes it possible to increase catching ability of produced track membrane with respect to low-density lipoproteins in human blood with preservation of albumin fraction.
