Abstract
In this work, the authors present the possibility of modification of polymer membranes by TiO(2) + AgO coating created by the magnetron sputtering method. The two-component TiO(2) + AgO coating can improve and shape new functional properties such as bactericidal and photocatalytic properties. The influence of magnetron power changes on the structure of the membrane was investigated as well. The structure and elemental composition of TiO(2) + AgO coatings were analyzed using SEM and EDS technique. All deposited coatings caused a total inhibition of the growth of two investigated colonies of Escherichia coli and Bacillus subtilis on the surface. The photocatalytic properties for membranes covered with oxide coatings were tested under UV irradiation and visible light. The filtration result show that polymer membranes covered with two-component TiO(2) + AgO coatings have a permeate flux similar to the non-coated membranes.
