摘　　要：以钛酸四丁酯、氨基纳米银为原料,采用溶胶-水热法合成了纳米TiO_(2)/Ag分散液,通过浸渍后整理法制备了纳米TiO_(2)/Ag负载海藻酸钙纤维,并对制备的纤维进行表征和抗菌性能测试。透射电镜扫描(TEM)、X射线衍射(XRD)、扫描电镜(SEM)和X射线光电子能谱(XPS)结果显示纳米TiO_(2)/Ag成功负载在海藻酸钙纤维表面。纳米TiO_(2)/Ag负载海藻酸钙纤维对大肠埃希菌和金黄葡萄球菌具有优异的抑菌性能,抗菌率大于99%。TiO_(2)/Ag dispersion is prepared using the sol-hydrothermal method with tetrabutyl titanate and amino Ag nanoparticles as raw materials.Subsequently,nano TiO_(2)/Ag-loaded calcium alginate fibre is prepared by impregnation.The prepared fiber is characterized and tested for antimicrobial properties.The results of transmission electron microscopy(TEM),X-ray diffraction(XRD),scanning electron microscopy(SEM),and X-ray photoelectron spectroscopy(XPS)demonstrat that the nano TiO_(2)/Ag is successfully loaded onto the calcium alginate fiber.The nano TiO_(2)/Ag-loaded calcium alginate fiber exhibites excellent antibacterial properties against Escherichia coli and Staphylococcus aureus,with an antibacterial rate exceeding 99%.
