Vibrational and corrosion properties of poly(dimethylsiloxane)-based protective coatings for AA 2024 modified with nanosized polyhedral oligomeric silsesquioxane
Source abstract
Abstract
Abstract The combined effect of hydrophobic poly(dimethylsiloxane) chains and polyhedral oligomeric silsesquioxanes in protective coatings for AA 2024 alloy was investigated using standard electrochemical techniques. The coatings were subjected to ex situ and in situ vibrational spectroscopies to follow the changes in the bands of protective coatings during forced anodic polarisation. The ex situ IR reflection–absorption measurements were performed under near-grazing conditions (80°), yielding changes mainly in the C–H stretching region. Confocal Raman measurements were made under in situ conditions in a specially designed spectroelectrochemical cell. The results that could be obtained with both vibrational techniques are presented.
