Abstract
A newly low-cost and environment-friendly process of surface activation on ABS plastic was carried out by employing a kind of biopolymer to
fix catalyst metal on the substrate by chemical sorption. The ABS foils after each step of pretreatment were investigated by XPS to understand the
reaction mechanisms. It is confirmed that the new method enhanced the adhesive strength of plating layer and substrate by chemical sorption,
instead of the physical sorption in the conventional sensitizing-activation method. Nickel deposition on the activated ABS surface started as soon
as it was dipped into an electroless nickel plating solution. A tight, dense and continuous structure of Ni–P plating player was obtained. The
microstructure appearances of the activated surface and Ni–P plating layer were characterized by SEM.
