利用固相反应法在十二烷基硫酸钠(SDS)存在下制备了盐酸掺杂聚苯胺,并以红外光谱(FT-IR),X射线衍射(XRD),循环伏安等测试方法研究了表面活性剂SDS对固相反应法制备盐酸掺杂聚苯胺的影响。结果表明:SDS存在下固相反应合成的盐酸掺杂聚苯胺与相同条件下盐酸掺杂聚苯胺相比,其分子链的氧化程度相对较小,结晶性、导电率及电化学活性相对较差。 The polyaniline doped with hydrochloric acid was prepared by solid phase reaction in the presence of sodium dodecyl sulfate (SDS). The properties of polyaniline doped with hydrochloric acid were investigated by FT-IR, XRD and cyclic voltammetry Effect of Surfactant SDS on Polyaniline Doped with Hydrochloric Acid by Solid - state Reaction. The results show that compared with hydrochloric acid doped polyaniline under the same conditions, polyaniline hydrochloride doped with hydrochloric acid synthesized by solid state reaction has a relatively small degree of oxidation of the molecular chain and relatively poor crystallinity, electrical conductivity and electrochemical activity .
