A novel approach of the deposition of two-component coating consisting of TiO and CuO on polymer membranes by MS-PVD method was presented in this work. This confirmed the possibility of using thin functional coatings for the modification of polymer membranes. The influence of technological parameters of the coating deposition on the membrane's structure, chemical composition and functional properties (hydrophilic, photocatalytic and bactericidal properties) were analyzed using SEM. Model microorganism such as and have been used to check the antibacterial properties. The results indicated that doping with CuO highlights the potential of bactericidal efficiency. The surface properties of the membranes were evaluated with the surface free energy. For evaluating photocatalytic properties, the UV and visible light were used. The filtration tests showed that polymer membranes treated with two-component TiO + CuO coatings have a permeate flux similar to the reference material (non-coated membrane). The obtained results constitute a very promising perspective of the potential application of magnetron sputtering for deposition of TiO + CuO coatings in the prevention of biofouling resulted from the membrane filtration of dairy wastewater.
本工作提出了一种通过磁控溅射物理气相沉积（MS-PVD）法在聚合物膜上沉积由TiO和CuO组成的双组分涂层的新方法。这证实了使用薄功能涂层对聚合物膜进行改性的可能性。利用扫描电子显微镜（SEM）分析了涂层沉积工艺参数对膜结构、化学成分和功能特性（亲水性、光催化和杀菌性能）的影响。已使用诸如[具体微生物名称1]和[具体微生物名称2]等模式微生物来检查抗菌性能。结果表明，掺杂CuO突出了杀菌效率的潜力。用表面自由能评估膜的表面性质。为评估光催化性能，使用了紫外光和可见光。过滤测试表明，用双组分TiO + CuO涂层处理的聚合物膜的渗透通量与参考材料（未涂层膜）相似。所得结果为磁控溅射在沉积TiO + CuO涂层以防止乳制品废水膜过滤产生生物污染方面的潜在应用构成了非常有前景的前景。
