Abstract
The disclosure provides methods and materials for imparting corrosion resistance to a substrate, as well as the corrosion-resistant substrates prepared accordingly. Compositions and methods include nonpyrolyzed, silicon-based polymer coatings prepared on substrates. The prepared coatings are highly stable and resistant to corrosion. The invention finds utility, for example, in the fields of surface and coating chemistry.The composition contains silicon-containing polymers having units of the following formulae:[R1Si(OH)O]k (III)[R1Si(OR10)O]m (IV)[R1SiO1.5]n (V)[R1Si(H)O]p (VI)[R2R3SiO]q (VII).
