摘要: Abstract Novel nano- and microstructures of polypyrrole were synthesized by an electrochemical template-free method on Nickel (Ni) electrode. Scanning Electron Microscope (SEM) study revealed micro-snails after the one-step potentiostatic electropolymerization pyrrole in aqueous alkaline solution. The influence anodic polarization time morphological, mechanistic characteristics these novel polymeric films was investigated. An appropriate mathematical model established showed that two simultaneous 2D growth instantaneous nucleation processes a successive 3D progressive mechanism are involved formation under diffusion control. Polypyrrole layers generated from appeared to be different overoxidation states X-ray Photoelectron analysis electroactivity modified Ni
