Epoxy resins, which are obtained by the curing reaction of epoxy- and amine-compounds mixture, have been often utilized in contact with metals. We herein report on the chemical composition of the epoxy resin in close proximity to the copper interface on the basis of a non-destructive method. The concentration of the amine component in the interfacial region was 2-fold higher than that in the bulk, and the interfacial enrichment extended over at least 10 nm.

铜界面处模型环氧树脂中胺组分的偏析

通过环氧树脂和胺化合物混合物的固化反应获得的环氧树脂经常用于与金属接触。我们在此基于非破坏性方法报告了靠近铜界面的环氧树脂的化学成分。界面区域中胺组分的浓度比本体中的浓度高 2 倍，并且界面富集范围至少扩展了 10 nm。
