The preparation of self‐assembled polyaniline (PANi) microspheres via facile interfacial oxidation polymerization of aniline in the presence of DL ‐tartaric acid dopant is reported. Compared with PANis reported in the literature, the PANi prepared in this study exhibits a nanorod‐bundle morphology with exceptionally high crystallinity. These nanorods or nanorod bundles can self‐assemble into microspheres with unique alignment. The chemistry, morphology, and crystal structure of DL ‐tartaric acid doped microspheres were studied using SEM, TEM, SAED, XRD, and FTIR.
