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。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.
