摘要: Abstract Polyethyleneimine films have been deposited on platinum electrode surfaces by electrochemical oxidation of ethylenediamine H2N–CH2–CH2–NH2 (EDA) in acetonitrile solutions. This synthesis was realized cyclic voltammetry and gravimetry techniques. Then, the characterization thin solid polyethyleneimine film performed using X-ray photoelectron spectroscopy infrared spectroscopy. It also shown, atomic force microscopy, that polymeric coating has a granular homogeneous structure. The influence EDA concentration electropolymerization process studied leading to conclusion reaction is easier for high concentration. nature supporting salt investigated, showing its not very important, contrary
