摘要：

提出一种制备三氧化钼/聚苯胺层状复合物的新方法，打破了传统制备方法对(Li/Na)_xMoO₃前驱体、离子引发剂以及水溶液环境的依赖.该方法使用烷基胺为插层剂在三氧化钼层间插入苯胺单体，然后在空气中热处理引发层间苯胺聚合形成三氧化钼/聚苯胺层状复合物.X射线衍射、扫描电子显微镜、差热分析及VSM磁性能测试结果表明,该复合物具有清晰层状形貌，层间聚苯胺以平行于层板形式存在,聚苯胺与三氧化钼在复合后磁性能发生明显变化.

Abstract:

A novel method is proposed for preparing MoO3/polyaniline composite with layered structure. The composite was prepared first by inserting aniline into MoO3 lattice using dodecylamineintercalated MoO3 as precursor, followed by successful polymerization in air. The composite was characterized by powder XRD, SEM, and TGA-DSC. A possible arrangement of intercalated aniline in the gallery of MoO3 is proposed. Its magnetic property has been studied by VSM at room temperature.

Key words: molybdenum trioxide; polyaniline; intercalation; layered material; magnestism
