Title: A study on the change of transport and selective properties of ultrafiltration polymer membranes after vacuum metallization with iron-chromium-nikel alloy
Keywords: SEM, pre-modification

Abstract: Polyacrylonitrile ( PAN ) ultrafiltration ( UF ) membranes are prepared by the phase inversion in a wet process. PAN membranes has the typical asymmetric structure. The possibility for vacuum metallization of ultrafiltration polymer membranes with iron-chromium-nickel alloy was studied after preliminary modification with Sn2+ in acid medium. The influence of pre-modification of polymer surface before the actual vacuum metallizing. The change of transport and selective characteristics of the vacuum metal coated membranes was studied, as well as the durability of the vacuum obtained coating during membrane performance. The metal coating was prepared by magnetron sputtering of iron – chromium – nickel alloy ( H18N9T ).The surface properties were investigated by scanning electron microscopy ( SEM ).
