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.

具有表面改性的环氧整体式粘结系统的界面结构控制和三维X射线成像。

整体式粘结系统对于异种材料粘结具有很高的可靠性。不管所用材料的相容性如何，在基材上制造的环氧整体料层都可通过锚固效应保证粘结强度。设计高性能整料粘结系统需要抑制整料和基材之间的界面破坏。在这项研究中，含有氨基和环氧基的硅烷和膦偶联剂用于在整体结构与玻璃和金属等基材之间构建牢固的界面结构。除了样品横截面的扫描电子显微镜外，还通过三维X射线成像作为无损观察方法来表征内部和界面整体结构。
