摘　　要：成功地以过硫酸铵为氧化剂,通过室温固相聚合反应法制备了聚吲哚。利用红外光谱(FT-IR)、紫外可见光谱(UV-vis)、X射线衍射(XRD)和循环伏安(C-V)等测试方法对聚吲哚进行了表征。发现氧化剂与单体的摩尔比为2时,聚合物的产率和电导率均较高。结果表明,吲哚单体固相聚合的方式比较多,但主要是发生在2,3位置,并且得到的聚合物具有良好的结晶性,同时也表现出一定的电化学活性。Polyindole was synthesized using ammonium peroxydisulfate as an oxidant by solid-state polymerization at room temperature. The fourier transform infrared （FT-IR） spectra, ultraviolet-visible （UV-vis） absorption spectra, X-ray diffraction （XRD） patterns and cyclic voltammetry （C-V） study were used to characterize the properties of polyindole. It was observed that yield and conductivity of polymer were higher when the molar ratio of oxidant to indole monomer was 2. The results revealed that polymerization mainly happened at the 2, 3- positions of indole molecule, and polyindole synthesized by solid-state polymerization displayed better crystallinity and good electrochemical properties.
