Fabrication of polyaniline nanorods on electro-etched carbon cloth and its electrochemical activities as electrode materials

In this work, polyaniline (PANI) nanorods were deposited on electro-etched carbon cloth (EC) by facile electrodeposition method with the existence of purified aniline and sulfuric acid. Various deposition potentials were applied to achieve a good electrochemical performance of EC-PANI electrode. Dif...
