摘　　要：在水热条件下合成了一系列具有Keggin结构的PMo_χ V_12-χ-CTAB（χ=9,10,11）复合材料（PMo_χ V_12-χ为具有不同配比的磷钼矾三元杂多酸,CTAB为十六烷基三甲基溴化铵）,采用FT-IR、XRD、TG、SEM对其进行了表征,采用抑菌圈法对大肠杆菌进行了抑菌活性研究。结果表明,杂多酸阴离子上的端氧与CTAB阳离子上的N＋间通过配合作用相互连结而形成复合材料,复合材料中仍保持有杂多阴离子的Keggin结构以及CTAB的基本结构,SEM分析表明,复合材料表面形貌为微米球形态,大多呈规则圆形,且分布均匀。随着V的含量增加,材料的稳定性及抑菌性能都有提高,分解温度较CTAB提高了200℃;抑菌效果是CTAB的2～3倍。A series of PMo_χ V_12-χCTAB（x = 9,10,11 ） composite materials with Keggin structure were prepared in hydrothermal condition PMo_χ V_12-χ： molybdovanadophosphoric triheteropolyacid with different mixing ratios, CTAB： cetyltrimethyl ammonium bromide）. The properties were investigated by FT-IR,XRD, TG and SEM. The bacteriostatie activities for eolibaeillus were studied using the inhibition zone method. The composite materials were formed by the oxygen in the heteropolyacid anion mating with the N ~ in CTAB cation, and they also contained Keggin structures and CTAB. The morphology of these composite materials were shown in micron spherical. Most of them were uniform spherical and uniform distribution. With the addition of V,the stability and the bacteriostatic activities were increased. The decomposition temperature increased to 200 ℃ and the bacteriostatic activities increased 2 ～ 3 times of CTAB.
