以氯化镁、氯化铜、氯化钙为原料,十六烷基三甲基溴化铵（CTAB）为分散剂,采用微波水热法合成了氧化镁-氧化铜-氧化钙复合材料;通过X射线衍射（XRD）、扫描电镜（SEM）、氮吸附（BET）等表征手段对样品进行了结构表征;利用最小抑菌浓度（MIC）和菌落计数法对样品的抗菌性能进行了研究。实验结果表明：氧化镁-氧化铜-氧化钙复合物具有纳米片状结构,制备的MgO0.7CuO0.1CaO0.2比表面积为66.789 m2/g,平均孔径为54.117 nm,孔容为0.904 cm3/（g·nm）;MgO0.7CuO0.1CaO0.2在质量浓度为500 μg/mL条件下展现出良好的抗菌性能,在质量浓度为600 μg/mL以上时抑菌率达到99.9%以上。

MgO-CuO-CaO composites were synthesized by microwave hydrothermal using MgCl2·6H2O,CuCl2·2H2O and CaCl2 as raw materials and CTAB as dispersant.The structures of the samples were characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM）,nitrogen adsorption（BET） and other characterization methods.The minimal inhibitory concentration（MIC） and colony count method were used to test the antibacterial properties of the samples.The results showed that MgO-CuO-CaO composites were nanoflake structure.The prepared MgO0.7CuO0.1CaO0.2 had a specific surface area of 66.789 m2/g,an average pore diameter of 54.117 nm and a pore volume of 0.904 cm3/（g·nm）.MgO0.7CuO0.1CaO0.2 showed excellent antibacterial properties at the concentration of 500 μg/mL,and the antibacterial rate reached more than 99.9% at the concentration of 600 μg/mL.
