摘要:
本研究采用反应磁控溅射技术制备了不同铜含量的CrNCu抗菌薄膜。台阶轮廓仪、扫描电镜、电子能谱和X射线衍射分析表明,随着铜靶电流的增大,薄膜的沉积速率和Cu含量升高,CrN和Cr含量下降,但粗糙度在0.9~1.4 nm之间。接触角测试表明CrNCu薄膜具有高疏水性和低表面能,其表面水滴的干燥时间长于玻璃试样。平板计数和模拟环境下的喷雾菌液实验表明,CrNCu薄膜对大肠杆菌具有良好的抗菌性能。
Abstract:
We prepared CrNCu antibacterial films with different copper content by reactive magnetron sputtering. Profilometer, SEM, EDX and XRD analyses showed that the deposition rate and Cu content increased, CrN and Cr contents decreased with the copper target current, but the film roughness was kept at 0.9~1.4 nm. Contact angle measurement showed that CrNCu films had high hydrophobicity and low surface energy, and the drying time of water droplet at the film surface was longer than that of glass sample. The tests of plate counting and spraying of bacterial suspension indicate that the CrNCu films have good antibacterial activity against E. coli.
