以全氟癸二酸(PFSEA)为掺杂剂,采用无模板法首次合成了由聚苯胺(PANI)一维纳米纤维组装而成的三维盒状微结构。三维盒状微结构显示出超疏水性和高结晶性。形成如此复杂的微/纳米结构的技巧在于,PFSEA不仅充当掺杂剂和软模板,而且还提供氢键和疏水性相互作用作为从一维纳米纤维自组装到3D盒状微结构的驱动力。由于低表面能全氟碳链和两个亲水性-COOH末端基团。
Three-dimensional boxlike microstructures assembled from 1D-nanofibers of polyaniline (PANI) were synthesized by a template-free method in the presence of perfluorosebacic acid (PFSEA) as the dopant for the first time. The 3D-boxlike microstructures show both super-hydrophobic and high-crystalline properties. The trick of forming such complex micro/nanostructures is that the PFSEA not only serves as both dopant and soft-template, but also provides hydrogen bond and hydrophobic interactions as driving forces for self-assembly from 1D-nanofibers to 3D-boxlike microstructures due to low-surface energy perfluorinated carbon chain and two hydrophilic –COOH end groups.
