Abstract
Corrosion is the degradation of a metal, which is caused by chemical reactions between the metal and its surroundings. It poses severe and inevitable problems to the long-term use of particularly copper-based materials in daily life due to the requirement of periodically replacement of it and the loss of its appearance. Therefore, it is necessary to apply a protective layer on them to extend the life span. In this study, inorganic-organic hybrid coatings comprising thiol functional silanes on copper sheets were obtained by spraying onto it followed by curing at elevated temperature. All coatings studied were optically transparent, smooth and crack-free. As they showed excellent adhesion to the copper surface, they were resistant to UV radiation and solutions of acidic and basic conditions. By the coating of copper sheets with hybrid coatings studied, both their mechanical durability and corrosion resistance in the salt spray test were considerably improved.
