中文摘要：
建立一种无模板的恒电位电聚合方法，可在室温下制备对甲基苯磺酸（p—TSA）掺杂的多级树状纳米结构聚苯胺（PANI）．根据电聚合曲线分析了PANI的聚合机理．扫描电镜（SEM）、透射电镜（TEM）观察表明制备的PANI具有均匀的多级树状纳米结构．紫外可见吸收光谱（UV-Vis）和红外光谱（FTIR）则显示所制备的PANI为掺杂态．该电沉积方法具有简便、易操作的特点，还可应用于其它纳米结构导电聚合物的可控制备．
英文摘要：
In this work, the p-TSA doped and hierarchical dendritic nanostructured polyanilines（PANI） have been prepared by potentiostatic electropolymerization without using any templates at room temperature. The mechanism of the polymerization has been discussed according to the electrodeposition curves. Scanning electron microscopy（SEM） and transmission electron microscopy（TEM） were employed to confirm the formation of uniform hierarchical dendritic structure on PANI. UV-Vis spectroscopy（UV-Vis） and infrared spectroscopy（FTIR） proved that the prepared PANI is in the form of emeraldine salt. The templateless electrodeposition method is simple, easy to operate, can be applied to fabricate other nanostructures of conducting polymers.
