In this work, the authors present the possibility of modification of polymer membranes by TiO + AgO coating created by the magnetron sputtering method. The two-component TiO + 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 + AgO coatings were analyzed using SEM and EDS technique. All deposited coatings caused a total inhibition of the growth of two investigated colonies of and 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 + AgO coatings have a permeate flux similar to the non-coated membranes.

在这项工作中，作者介绍了通过磁控溅射法制备的TiO + AgO涂层对聚合物膜进行改性的可能性。双组分TiO + AgO涂层可以改善并形成新的功能特性，如杀菌和光催化性能。还研究了磁控功率变化对膜结构的影响。使用扫描电子显微镜（SEM）和能谱仪（EDS）技术分析了TiO + AgO涂层的结构和元素组成。所有沉积涂层均导致表面上所研究的两种菌落的生长完全受到抑制。在紫外线照射和可见光下测试了覆盖有氧化物涂层的膜的光催化性能。过滤结果表明，覆盖有双组分TiO + AgO涂层的聚合物膜的渗透通量与未涂层的膜相似。
