Title: Adhesion promotion of composite interfaces and corrosion protection for metal surfaces by using silane derivatives

Thesis/Dissertation ·
OSTI ID:5657459

Fourier transform infrared spectroscopy (FT-IR) is utilized to study the adhesion promotion of composite interfaces as well as the coating materials for the corrosion protection of metal substrate. Adsorption behavior, hydrophobicity, solution property, the reactivity of C=C bond, and chain flexibility of silane backbone are important factors for determining the mechanical property of unsaturated polyester composites. As the number of methylene space group increases gradually, silane molecules are adsorbed with silica slightly bowed with respect to the surface. Modified poly-N-vinylimidazole(PVI(1)) is demonstrated to apply for new anticorrosion agent for copper substrate under wet and dry condition. In the case of modified PVI(1), corrosion formation of copper surface is suppressed even at 80{degree}C for 24 h in 100% relative humidity. PVI(1) is also effective for corrosion protection of copper substrate at 360{degree}C. For the corrosion protection of steel surface, silane coupling agents have been applied for the epoxy/steel system. The degree of corrosion depends on the epoxy thickness, the inherent properties of silanes, and the chemical linkages at the silane/epoxy and the silane/steel interfaces.
