摘　　要：以乙二胺四乙酸为掺杂剂,过硫酸铵为氧化剂,采用自组装的方法合成了掺杂态的聚苯胺纳米管。通过扫描电镜(SEM),透射电镜(TEM),红外光谱(IR),X射线衍射(XRD),UV-Vis和四探针法等测试手段对产物的形貌、结构和性能进行了表征。分析了不同乙二胺四乙酸和苯胺的摩尔比对产物的形貌和导电性能的影响。结果表明,不同乙二胺四乙酸和苯胺的摩尔比对产物有一定的影响,随着摩尔比的增加,产物纳米管的直径增大;合成的聚苯胺纳米管具有一定的导电性。Doped polyaniline（PANI） nanostructure has been prepared at room temperature using ethylenediaminetet macetic acid（EDTA） as dopant and ammonium persulfate（APS） as oxidant by a self-assembly method.The morphology,structure and property of polyaniline nanostructure were characterized by scanning electron microscope（SEM）,transmission electron microscope（TEM）,infrared spectrum（IR）,X-ray diffraction（XRD）,UV-Vis and applying the 4 probes method.Effect of molar ratio of EDTA to AN on the morphology and electric conductivity was studied.It is found that the morphology and electric conductivity obtained product are affected by the different molar ratio of EDTA to AN.The diameters of polyaniline nanotubes at room-temperature increase with the increase of / ratios.Doped polyaniline nanostubes possess electric conductivity.
