FE-SEM images (top images) together with their EDS analyses (bottom images) of hybrid PPy-Ni(OH)2 nanowires formed at different durations of the cathodic potential pulse. The duration of the cathodic pulse was (a) 100 s and (b) 600 s. The duration of the anodic pulse was 10 s for (a) and (b). The presence of Ni(OH)2 nanoparticles is marked with red ellipses.
