以层状钨基氧化物(H2W2O7)为无机主体,用正庚胺改性后的正庚胺/H2W2O7复合物(HTT)为中间体,通过离子交换、层间O2引发聚合等步骤成功制备了聚苯胺/H2W2O7层状复合材料(PANI/H2W2O7).X射线衍射、扫描电子显微镜、红外光谱及差热分析结果表明:聚苯胺分子已成功地嵌入H2W2O7层间,层状结构没被破坏,层间距变至1.19nm;聚苯胺的嵌入还大大提高了材料的热稳定性.讨论了无机主体与有机客体之间的相互作用、聚苯胺在层间的排布形式及苯胺和聚苯胺插入层间的反应机理.
The layered tungsten-based oxide (H2W2O7) was used as the inorganic host and the n-heptylamine / H2W2O7 complex (HTT) modified by n-heptylamine was used as the intermediate to prepare the Polyaniline / H2W2O7 layered composite (PANI / H2W2O7). X-ray diffraction, scanning electron microscopy, infrared spectroscopy and differential thermal analysis show that polyaniline molecules have been successfully intercalated into H2W2O7 layers, The spacing becomes 1.19nm; the polyaniline embedding also greatly improves the thermal stability of the material.It discusses the interaction between inorganic host and organic guest, the distribution of polyaniline in the layer and the interposition of aniline and polyaniline The reaction mechanism.
