“…Dissimilar material bonding attracts much attention in many application fields including automobiles, aircrafts, and electronics since polymer and composite materials have been used as the substitution of metal and inorganic materials to lighten weight and save energy. − Several surface modification processes are effectively used to achieve reliable adhesion and interaction at the interface. − An anchor effect is one of the most important mechanical, chemical, and physical interactions for adhesion between various materials. Chemical etching and laser radiation are commonly used to create porous surface structures on the adherend, being advancing as one of the most convenient and reliable bonding technologies using anchor effects. ,− However, these techniques require special chemicals and equipment.…”

A monolith bonding system has a high reliability for dissimilar material bonding. The epoxy monolith layer fabricated on a substrate guarantees bond strength by the anchor effect, regardless of the compatibility of the used materials. Designing a high-performance monolith bonding system requires the suppression of an interfacial failure between the monolith and the substrate. In this study, silane and phosphine coupling agents containing amino and epoxy groups were used to construct a robust interfacial structure between the monolith and the substrates such as glass and metals. The internal and interfacial monolith structures were characterized by three-dimensional X-ray imaging as a nondestructive observation method in addition to the scanning electron microscopy of the sample cross sections. The modification of the substrate−monolith interface using the coupling agents improved the strength of dissimilar material bonding of the glass and metal substrates in combination with thermoplastic resins such as poly(ethylene terephthalate) and polycarbonate bisphenol-A.
