聚苯胺/MCM-41介孔分子筛导电复合材料的制备及其表征

Preparation and characterization of polyaniline/MCM-41 zeolite conductive composite

利用MCM-41介孔分子筛单分散孔道特性作为“纳米反应器”,在其孔道内合成聚苯胺。讨论了HCl浓度、(NH4)2S2O8浓度和聚合温度对复合材料导电性的影响,得到最佳的聚合条件:HCl:1.5mol/L,(NH4)2S2O8:1.0mol/L,聚合温度:15℃,此时的电导率为0.61s/cm。在最佳合成条件下,对聚苯胺/MCM-41介孔分子筛导电复合材料进行SEM、红外光谱分析。

Using the aperture of MCM-41 zeolite composed polyaniline. In this experimentation, we discussed the infection about the concentration of HCI, （NH4）2SZO8 and the temperature, found the best condition： HCl. 1. 5mol/1 （NH4）2 S2O8 1.0mol/l, temperature： 15 ℃, the conductance was 0. 61S/cm. Analysis instrument： SEM, FTIR.
