Highly crystalline uniform nano structured poly aniline doped with H2SO4

In this contribution, highly crystalline, uniform rod-like nanostructured polyanilines, ca. 100–150 nm in diameter and 500–900 nm in length were successfully synthesized by chemical polymerization by both stirring and without stirring the reaction system at 0°C and room temperature in acidic medium(H2SO4). Resulted polymerswere characterized byUV-Vis, Fourier transform infrared (FT-IR), proton-nuclear magnetic resonance (1HNMR) and X-ray diffraction (XRD) techniques. Two distinctive morphologies, rod like and grain like structures were observed as confirmed unambiguously by scanning electron microscopy (SEM) by stirring and without stirring the reaction respectively.We have evaluated their conductivity by dc electrical conductivity measurements and thermal properties by thermogravimetric analysis (TGA).
