Scan rate dependent morphology of polyaniline films electrochemically deposited on nickel
A Kellenberger, D Ambros, N Plesu - International Journal of …, 2014 - Elsevier
The effect of scan rate on the morphology and properties of polyaniline has been
investigated for samples deposited electrochemically on nickel from sulfuric acid solution. A
nanofibrilar network structure has been obtained for low scan rates (10, 25 and 50 mV s-1)
whereas for the highest scan rate (100 mV s-1) the structure was more compact, the
nanofibrils aggregated and their features were not very obvious. Both diameter and length of
nanofibers are scan rate dependent, decreasing from 140 to 90 nm and from 1.35 to 0.72 μm …
