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(613 nm)，其荧光寿命为441.32 μs；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。

A fluorescent and conductive composite material was formed by doping Eu-containing hydrotalcite-like 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.
