介孔复合体是目前纳米材料研究领域的前沿和热点 ,本文采用纳米级介孔材料(SiO2 、Al2 O3 )为载体 ,利用浸渍法 ,将金属阳离子Ag+、Cu2 +、Zn2 +组装到介孔材料中 ,制成无机抗菌材料 ,并对抑菌性能进行了评价。同时 ,作为对比用同样方法制备了以微米级的活性SiO2 为载体的介孔复合体 ,并对其抗菌性能进行评价。结果发现纳米级介孔复合体的抗菌性能优于微米介孔复合体 Mesoporous composites are the forefront and hotspot in the field of nanomaterials research. In this paper, nanosized mesoporous materials (SiO2, Al2 O3) were used as supports, and the metal cations Ag +, Cu2 + and Zn2 + were assembled into mesoporous materials , Made of inorganic antibacterial materials, and antibacterial properties were evaluated. At the same time, the mesoporous composite with micron SiO2 as carrier was prepared by the same method and its antibacterial property was evaluated. The results showed that the antibacterial performance of nano-mesoporous composite is better than that of micro-mesoporous composite
