Description
Summary:Electrochemical oxidation of ethylenediamine leads to the coating of different electrode surfaces by a thin polymeric film. This film was characterized as a polyethylenimine one using both spectroscopic methods such as infrared-attenuated total reflection or infrared absorption spectroscopy and ab initio calculations. More, since the polymeric coating changes the electrochemical behavior of different surfaces, this film can be used successfully to make new chemical sensors.
