COMPOSITE POLYMER MEMBRANE AND METHOD OF ITS PRODUCTION

摘要

A double composite polymer membrane with antibacterial properties contains a porous support (polyvilidene fluoride or polysulphone, or polyether) and applied polymeric layer on the basis of quaternaryammonium salts. The membrane is obtained via forming of the polymeric layer on the porous support from the solution of quaternary ammonium salts with concentration of 0.3-3 M followed by irradiation by ultraviolet light with intensity of 0.5-1.7 mV/cm2. The composite polymer membrane has a high antibacterial activity (AA - 82.4-99.4 %) and output G - 6.4-7.8 m3/m2 per hour, which allows using it effectively in the processes of purification of water.
