Characterization of silane layers on modified stainless steel surfaces and related stainless steel-plastic hybrids

► AFM, FESEM, and TEM are useful to obtain quantitative information on silane layers. ► Information on layers can be linked to adhesion and failure type of hybrids. ► Controlled Fe2O3-type surface is needed to achieve uniform silane layer. ► Silane layer on controlled oxide layer has more N-species to react with plastic.
