环氧树脂，其通过环氧化合物和胺化合物混合物的固化反应获得，经常用于与金属接触。我们在此报告的化学组成的环氧树脂在接近铜界面的基础上的非破坏性的方法。在界面区域中的胺组分的浓度比在本体中的浓度高2倍，并且界面富集延伸超过至少10 nm。
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.
