Uniform rice-like nanostructured polyanilines with highly crystallinity prepared in dodecylbenzene sulfonic acid micelles

Highly crystalline polyanilines (PAni) with uniform rice-like nanostructures, ca. 50–130 nm in diameter and 130–260 nm in length were successfully prepared in the presence of dodecylbenzene sulfonic acid (DBSA) without stirring, and characterized by SEM, FTIR, UV–vis and XRD measurements. The formation of aniline/DBSA salts insoluble in reaction system without stirring is believed to be favorable for the formation of this uniform rice-like nanostructures.
