Facile Synthesis of Flexible Hollow Conductive Polyaniline Composite Fibers from Willow Catkins

ABSTRACT

Catkin fibers, the white hairs on the seeds of willow, can float with the wind and send the seeds to a distant place. In this communication, flexible polyaniline/catkin composite fibers were prepared through in situ polymerization. Aniline was absorbed and polymerized on willow fibers, forming conductive hollow composite fibers. The as-prepared composite fibers show good conductivity of 10⁻¹ S/cm. The composite fibers can be easily compressed into tablets, twisted together forming a rope, and bent at any angle. This good flexibility will be found potential application in the field of flexible electronic devices.

摘要

柳树种子上的白毛柳絮纤维，能随风飘浮，将种子送至远方，通过原位聚合制备了柔性聚苯胺/柳絮复合纤维.苯胺在柳树纤维上吸附聚合，形成导电中空复合纤维.制备的复合纤维具有10⁻¹S/cm的良好导电性.复合纤维可以很容易地压缩成片剂，扭绞在一起形成绳索，并以任何角度弯曲.这种良好的柔性将在柔性电子器件领域得到潜在的应用.
