摘要：

This paper describes a molecular-dynamics study on the relationship between lattice mismatch and adhesion strength of interfaces between organic materials and metals. Aromatic resins with benzene-ring connected structures are used as examples of organic materials. A lattice constant of the aromatic resins is defined as the distance between the second nearest neighbors of a benzene ring. The value of the lattice constant of a wholly aromatic polyester resin is about 0.24 nm. On the other hand, a lattice constant of face-centered-cubic structured metals is defined as the distance between the nearest neighbors. The lattice constants of copper and silver are about 0.255 nm and 0.29 nm, respectively. The adhesion of aromatic polyester resin with copper is stronger than that with silver because the lattice mismatch of the resin with copper is smaller than that with silver. Reducing the lattice mismatch is found to be effective in strengthening the adhesion. ©2009 The Society of Materials Science, Japan.
