Synthesis and Characterization of Elongated Chain-like Nanostructure Polyaniline in Ice Cube

Highly crystalline polyaniline (PANI) with elongated chain-like nanostructures 20-35 nm in diameter and 60-80 nm in length were prepared using sodium dodecylbenzenesulfonic acid (SDBSA) in ice medium withoutstirring. The synthesized polyanilines were characterized by SEM, FTIR, and UV-Visible spectroscopy andXRD measurements. The formation of polyaniline/SDBSA salts insoluble in reaction system without stirring isfound to be favourable for the formation of this clustered chain-like nanostructure. The temperature dependentconductivity measurement shows a thermally activated exponential behaviour of the chain-like polyanilinenanostructure. The melting point of the nanostructured polyaniline was found to be 253 °C.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at

Dr. András Paszternák, founder of Nanopaprika
