摘　　要：用快速原位聚合工艺制备了盐酸(HCl)和对甲苯磺酸(TSA)共掺杂聚苯胺(PANI)/凹土(ATP)纳米复合材料。通过正交实验确定了最佳反应条件,并用紫外-可见光谱、热重-差热分析、X射线衍射、Fourier红外光谱、透射电镜等对最佳条件下所得的纳米复合材料进行了表征。结果表明:HCl和TSA的混酸环境能快速实现苯胺的聚合及聚苯胺的掺杂,所生成的聚苯胺以晶态形式包覆在凹土的表面,并在物理作用下与凹土形成了纳米核壳结构纳米复合材料;纳米复合材料中聚苯胺的包覆率为23.49%,与纯HCl和TSA共掺杂聚苯胺相比,纳米复合材料的耐热性能得到提高。The polysniline （ PANI ）/attapulgite （ATP） nanocomposites co-doped with hydrochloric acid（HCl） and p-toluene sulphonic acid（TSA） were prepared by in situ fast polymerization method. The best reaction condition was obtained through orthogonal experiments, and nanocomposites prepared under the best condition was characterized by ultraviolet-visible （UV-Vis）, thermalgravimetry-differential thermal analysis（TG - DTA）, X - ray diffraction（XRD）, Fourier transform infrared spectroscopy （FTIR）, transmission electron microscopy （TEM）. The results showed that the polymerization of aniline and doping reaction of polyaniline were completed quickly in the hybrid acids consisting of HCl and TSA, the crystalline polyaniline as prepared encapsulates on the surface of attapulgite, forming the ＂core-shall＂ fibrous nanostructure under the physical interaction. The coveting ratio of polyaniline in nanocomposites is about 23. 49 %, and the heat resistance of nanocomposites is higher than pure HCl and SSA co-doped polyaniline.
