Abstract

Abstract: 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 1 H NMR experiments are executed to investigate the structures of final products. Abstract : Polyaniline nanowires and nanorods are synthesized through adjusting the concentration of NaF or/and D‐camphor‐10‐sulfonic acid (CSA) under the application of the electric field (30 V), when inorganic salt NaF is introduced into the initial solution containing aniline and CSA. The different morphologies of as‐prepared polyaniline are characterized by transmission electron microscopy and displayed as follows.
