摘要： 采用界面聚合和无模板法相结合的方法, 以具有疏水链的全氟癸二酸(PFSEA)为掺杂剂, 通过调节苯胺单体和FeCl3氧化剂的浓度实现了聚苯胺三维微/纳米结构形貌和尺寸的可控制备. 扫描电子显微镜测量结果显示, 聚苯胺是由一维纳米纤维自组装形成的三维微球结构; 红外吸收光谱和紫外-可见吸收光谱结果表明, 聚苯胺微球为掺杂态. 室温下, 该微/纳米结构聚苯胺微球的电导率为 9.6×10-3 S/cm, 表面水接触角为161.4°, 表现出半导体特性和超疏水性.

Abstract: Three-dimensional(3D) micro/nanostructures of polyaniline(PANI) were self-assembled by template-free method combined with interfacial polymerization in the presence of perfluorosebacic acid(PFSEA) as dopant. The 3D micro/nanostructures of PANI show both electrical conductivity and superhydrophobicity. It was proposed that the aniline filled bi-layer micelles composed of PFSEA/An salt were served as the soft-templates of the self-assembled nanofibers, then those nanofibers were self-assembled to form 3D-microstructures by the intermolecular interactions including hydrogen bonding and hydrophobic interaction as the driving forces. Moreover, their morphology and size can be controlled by changing the concentration and the molar ratio of aniline and oxidant. The method is a facile approach to prepare conducting polymer 3D architectures assembled by 1D-nanostructure.

Key words: Conducting polyaniline, Interfacial polymerization, Three-dimensional micro/nanostructure, Superhydrophobicity
