Microstructure and cohesion of thin ZnO interlayers in metal-duromer heterostructures

The present study is concerned with an investigation of the mechanical stability of a copper substrate-highly filled duromer structure. The adhesive strength between copper and duromer is remarkably enhanced by the existence of a thin ZnO primer layer. The microstructure of the interlayer is characterized be needle -like and plate-like particles which are identified by EDXS and EELSas Zinc oxide. A model is developed to explain the formed microstructure of the Zinc oxide interlayer.
