Ag对Ag-ZnO纳米抗菌涂层微观结构和性能的影响
Effect of Ag on the microstructure and performance of Ag-ZnO nanoscale antibacterial coatings
摘要
Abstract
External fixators,as the most common fixation devices,are widely used in open bone fracture surgeries.However,screws used in conjunction with external fixators are susceptible to infection.Utilizing radio frequency magnetron sputtering technology to prepare Ag-ZnO/Ti nano-composite coatings adhered to the surface of Ti6Al4V screws,it is possible to effectively reduce bacterial adhesion.By adjusting the ratio of target material bonding,the effect of the microstructure of different Ag content in composite coatings on the antibacterial performance of Ti6Al4V screws were investigated.The results indicate that when the volume ratio of Ag,ZnO,Ti target materials are 2:2:96,the mass fraction of Ag in the Ag-ZnO/Ti nanocomposite coating reaches 1.85%,with a roughness of 4.24 nm.The coating surface is smooth and hydrophobic,which is conducive to reducing bacterial adhesion.The cytotoxicity of the coating meets the biosafety standard,with the antibacterial rate as high as 99.62%.关键词
