采用化学氧化法,以十六烷基三甲基溴化铵(CTAB)为软模板,过硫酸铵(APS)为氧化剂,在CTAB/正戊醇/吡咯/水构成的微乳液体系中,合成了笔直有序的导电聚吡咯微米棒。运用傅里叶红外光谱(FTIR)对产物结构进行了分析,表明合成的产物为聚吡咯。运用透射电镜(TEM)对产物的形貌进行了表征,并讨论了反应温度、氧化剂的加入方式、助表面活性剂用量对产物形貌的影响。结果表明,在室温25℃,氧化剂滴加速度为1.5 h,表面活性剂CTAB与助表面活性剂正戊醇的质量比为0.6∶1.0,反应时间为24 h时,可获得直径约为300 nm,长度约为20μm的笔直有序的聚吡咯微米棒。
The chemical oxidation method was used to synthesize CTAB / n-amyl alcohol / pyrrole / water microemulsion system with cetyltrimethylammonium bromide (CTAB) as soft template and ammonium persulfate (APS) as oxidant. The straight and orderly conductive polypyrrole microrods. The product structure was analyzed by Fourier transform infrared spectroscopy (FTIR), indicating that the synthesized product was polypyrrole. The morphology of the product was characterized by transmission electron microscopy (TEM). The effects of reaction temperature, the addition of oxidant and the amount of cosurfactant on the morphology of the product were discussed. The results showed that when the mass ratio of CTAB to n-amyl alcohol was 0.6:1.0 and the reaction time was 24 h at 25 ℃, the diameter of oxidant was about 1.5 h, Straightly ordered polypyrrole microrods with a length of about 20 μm.
