摘　　要：以三嵌段共聚物P123为模板,通过溶剂蒸发诱导自组装技术(EISA),以硝酸铈和硝酸铜为原料,合成CuO/CeO2稀土复合抗菌材料,比较了无机原料摩尔比对产物微观结构和抗菌性能的影响。当CuO/CeO2比例等于0.15∶0.85时,复合材料为固溶体材料,且比表面积最大为125.7 m2·g-1,抗菌缓释时间最长达66 h以上。当氧化铜含量升高后,氧化铜从固溶体中析出,大大缩短了抗菌的缓释时间;当氧化铜含量降低时,复合材料的比表面积随之减少,影响了长效抗菌性能。With the evaporation-induced self assembly （EISA） method, mesoporous CuO/CeO2 rare earth an-tibacterial materials were synthesized by using cerium nitrate and copper nitrate as raw materials and P123 as surfactants. Besides,we explored the effects of inorganic raw material mole ratio on their micro structure and an-tibacterial properties. When the proportion of CuO/CeO2 was 0.15∶0.85,the composite was solid solution material. Its largest specific surface area was 125.7 m2·g-1,and its longest antibacterial release time was above 66 hours. When the cupric oxide content rose, copper oxide particles precipitated from the solid solution and the antibacte-rial release time greatly descended. When the content of copper oxide was reduced, the specific surface area of the composite was consequently lowered, which affected the long-acting antibacterial properties.
