Abstract

Abstract:

The symmetrical and low activity molecular structure of PPO substrate makes it has very stable chemical properties. Therefore, it is difficult to deposit high quality metal layer on the substrate surface by electroless plating. In order to solve this problem, chemical etched and dopamine grafting are combined to treat the surface of the PPO substrate to adjust the surface roughness and improve the surface hydrophilicity. Meanwhile, the conductivity and adhesion of the deposited metal layer are improved by introducing active functional groups that have an adsorption effect on Ag⁺. Characterization tests prove that the copper layer prepared by this method shows a continuous, uniform and densely packed morphology, and has high purity, good crystallinity, excellent adhesion and low resistivity.

Key words: polyphenylene ether, surface modification, roughness, dopamine, metal layer, chemical plating, conductivity, adhesion
