摘　　要：采用溶胶-凝胶法制备了SbxZn1-xO1+x/2及其壳聚糖的复配物,通过X-射线衍射仪(XRD)、傅里叶变换红外光谱仪(FTIR)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)等表征了样品的物相结构、组成和微观形貌。以大肠杆菌、白色念珠菌和金黄色葡萄球菌为测试菌种,研究了样品的抗菌性能。结果表明,SbxZn1-xO1+x/2的抗菌活性优于纯ZnO,其中x=0.05的样品活性最好;复配物的抗菌活性明显优于单一组分,当Sb0.05Zn0.95O1.025和壳聚糖质量比mSZ/mCS=2时,样品抗菌性能最佳。New SbxZn1-xO1＋x/2 and its composites with chitosan （CS） were prepared by the method of Sol-Gel. The phase structures, composition and morphologies of the samples were characterized by the X-ray diffraction （XRD）, the Fourier transform infrared spectroscopy （FTIR） and scanning electron microscopy （SEM）. The antibacterial properties of the samples were studied on Escherichia coli, Candida albicans and Staphylococcus aureus. The results showed that the antibacterial activities of the SbxZn1-xO1＋x/2 were better than that of ZnO. In which, sample of x=0.05 （SZ）had the best antibacterial activities. The SZ/CS composites were significantly better than each component in the antibacterial activity, and reached to the optimum when the mass ratio of SZ and CS was up to 2：1.
