中文摘要：

采用超声法将定量的荧光性含铕类水滑石（Eu-HTLc）掺混到导电性聚苯胺（PAN-CSA）中,获得一类新型的含铕类水滑石/聚苯胺导电性荧光复合材料（Eu-HTLc/PAN-CSA）。采用电导率测试、荧光光谱、红外光谱、X射线衍射和热分析等手段对其进行表征。研究结果表明：该复合材料的电导率σ=7.97×10-3（S/cm）;在紫外光下该复合材料可发出红色荧光（613nm）,其荧光寿命为441.32μs;热分析结果显示,该复合材料比PAN-CSA具有更高热稳定性,有望作为一类新型荧光材料而获得应用。

英文摘要：

A fluorescent and conductive composite material was formed by doping Eu-containing hydrotalcitelike compound in the polyaniline.The structure and properties have been characterized with electrical conductivity methods,fluorescence spectrum,FT-IR techniques,X-ray diffraction（XRD） and thermogravimetric analysis（TG）.The results showed that the composite material was a semiconductor material which had good fluorescence propertics.Otherwise,the composite material had better thermal stability than the relevant PAN-CSA.The composite material may become a promising candidate for new fluorescent materials.
