摘　　要：以硫酸铜(CuSO4)为催化剂,H2O2为氧化剂,通过"无模板"化学氧化聚合制备出聚苯胺纳米纤维。研究了温度、H2O2的浓度、催化剂的浓度对聚苯胺的产率、电导率、反应速度的影响,确定出最佳聚合反应条件为:苯胺0.1 mol/L,盐酸1 mol/L,H2O2 0.15 mol/L,CuSO40.05 mol/L,反应时间为24小时。在此条件下合成聚苯胺的产率为58.2%,电导率为1.98 S/cm。红外光谱和紫外-可见光谱确定了合成聚苯胺的结构,扫描电镜图中发现制备导电聚苯胺呈纤维状,直径大约为60~80 nm,长度大约为400 nm。With CuSO4 as catalyst, H2O2, as oxidant, polyaniline nano-fibers were prepared with ＂no template＂ chemical oxidative polymerization. The effect of reaction temperature, concentration of H2O2, concentration of catalyst to the yield of polyaniline, conductivity, and the reaction rate was studied. The optimum polymerization conditions were obtained as follows： 0.1 mol/L aniline, 1 mot/L HCL, 0.15 mol/L H2O2, CuSO4 0.05 mol/L, and the reaction time for 24 hours. The yield of potyaniline was 58.2 % and the conductivity was 1.98 S/cm under optimum polymerization. FTIR and UV-Vis spectra determined the structure of the synthesis of polyaniline. The synthesized polyaniline had nano-fibers morphology, about 60-80 nm in diameter, 400 nm in length observed by scanning electron microscopy.
