Effect of Silane Coupling Agent on Bonding Strength of Polymer Film to 316L Stainless Steel

In this paper, surface pretreatment of 316L stainless steel by silane coupling agent was carried out in order to improve bonding strength between the substrate and polymer. RAIR was employed to evaluate the surface character. The results showed that different concentrations, dipping time, pH value, and aging methods of silane coupling agent were proposed as important factors affecting bonding strength of the polymer to the metal surface.
