Synthesis of Polyaniline Nanowires and Nanorods in the Presence of NaF under an Electric Field and Their Characterization

In this work, polyaniline nanowires and nanorods are synthesized through adjusting and controlling the concentration of D‐camphor‐10‐sulfonic acid (CSA) and NaF salt under the application of an electric field. The morphologies and structures of as‐synthesized polyaniline (PANI) are characterized through various methods, including transmission electron microscopy, UV–vis, Fouier transform infrared spectroscopy, and X‐ray diffraction. The results demonstrate that the introduction of an electric field can improve the crystallinity of PANI, and PANI nanowires/nanorods are fabricated through changing the amount of NaF or CSA in the presence of the electric field. Besides, the ¹H NMR experiments are executed to investigate the structures of final products.
