Caratterizzazione elettrochimica di silanoli organo-funzionalizzati come precursori per trattamenti superficiali=Electrochemical characterization of organo-functionalized silanes as precursors for surface treatments

Previous studies, performed with silanes functionalized with pyrrole and aniline as precursors for corrosion protection, showed that these hybrid molecules provide both barrier and auto-regenerative actions. The present work investigates the electrochemical behavior of these silanes in order to elucidate possible correlations between structure and redox properties. The films were electrochemically deposited on glassy carbon and/or platinum electrodes, using tetrabutylammonium perchlorate in acetonitrile as supporting electrolyte. Characterization techniques such as cyclic voltammetry, Vis, ATR, indicated that the redox properties are influenced by the nature of the organic functional group and the extent of hydrolysis of the methoxysilyl group.
