摘要/Abstract

摘要： 采用溶胶凝胶-浸渍提拉法,制备了玻璃基底上生长的Fe/TiO₂薄膜.利用XRD、XPS、AFM等对样品进行表征,研究了铁掺杂对TiO₂薄膜晶体结构和表面形貌的影响,并研究了不同掺铁量TiO₂薄膜对大肠杆菌的抗菌性能.结果表明,铁掺杂TiO₂薄膜的抗菌性能均优于纯TiO₂薄膜,其中掺铁量为0.1%时薄膜的抗菌性能最佳,高达98%.

关键词: Fe/TiO₂薄膜, 溶胶凝胶法, 浸渍提拉法, 抗菌性能

Abstract: Fe/TiO₂ films were prepared by the sol-gel and dip-coating method on glass substrate.The as-prepared samples were characterized by XRD,XPS and AFM.The influence of Fe-doping content on lattice structure and surface morphology for TiO₂ films was studied.At the same time,the antibacterial properties of E.coli of TiO₂ films doped with different iron content were also studied.The results showed that the antibacterial properties of the Fe/TiO₂ films is better than pure TiO₂ films,especially when the content of Fe-doped is 0.1%,the antibacterial properties was the best,which reached up to 98%.

Key words: Fe/TiO₂ films, sol-gel method, dip-coating method, antibacterial properties
