Conducting polyaniline nanofiber networks prepared by the doping induction of camphor sulfonic acid

Abstract

AbstractBranched nanofibers of conducting polyaniline (PANI) buried in the crystals of camphor sulfonic acid (CSA) were prepared from an m‐cresol solution of PANI and excessive CSA. After the excessive CSA was dissolved through ultrasonication in deionized water, networks of PANI nanofibers with spherical nodes, nanoparticles, leaf‐vein‐shaped nanofibers, and so forth were obtained according to the strength of the ultrasonic treatment. The X‐ray diffraction patterns of the CSA‐doped PANI showed high crystallinity. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 87: 1537–1540, 2003
