We report on the ability of various coatings, prepared from model organofunctional silanes of form (C3H7)Si(CH3)n(OH)3-n, where n = 1,2 or 3, to provide a barrier to corrosion. These coatings have been characterised with electrochemical impedance spectroscopy (EIS) and X-ray Photoelectron Spectroscopy (XPS) measurements. Surface coatings from pH 2 and 4 aqueous solutions of these materials have been formed on the native oxide of aluminium, and studied with XPS at Flinders and EIS at LaTrobe. Our results show an interesting correlation between the number of active silanol species and the corrosion performance of the respective coating.
