Abstract

Highly crystalline polyaniline (PANI) nanotubes and nanofibers ca. 80–170 nm in diameter are successfully prepared by a “micelle soft‐template” method in the presence of dicarboxylic acids dopants with different numbers (n) of –CH~2~– groups (n = 0–4). It is found that the diameter of the nanostructures increases on increasing the number of –CH~2~– groups in the dicarboxylic acids. The conductivity of the nanostructures increases as their diameters decrease, showing that size has an effect on conductivity. A narrow peak at 2θ = 6.50° is observed in the X‐ray diffraction pattern, indicating that the distance in the direction perpendicular to the polymer chain increases as the number of –CH~2~– groups increases.
