Study of Adhesion Mechanism by Electron Microscopy

Abstract

For the study of the mechanism behind the adhesion phenomena, the adhesion interfaces were analyzed

by electron microscopy. Especially, scanning transmission electron macroscopy（ STEM） with energy dispersive

X-ray spectrometry（ EDX） and electron energy loss spectroscopy（ EELS） were performed for the local

chemical analysis of interfaces. Moreover, STEM-tomography was employed for the three-dimensional analysis

of interfaces. Polymer/metal joints obtained by injection molding, polymer/polymer interfaces formed via

interdiffusion, and polymer/metal bonded interfaces by hot-pressing were investigated. We have found the

common events that were occurred in the failure both of metal/polymer and polymer/polymer interfaces.
