ABSTRACT
It has been well accepted that an interphase, which may exist between the adherend and bulk adhesive in an adhesively-bonded joint, would play an important role in the performance of a bonded joint. The interphase would have properties different from those of the bulk adhesive. It may be formed spontaneously between the adherend and adhesive or may be intentionally introduced, for example, by using a surface pretreatment or through the use of coupling agents.
