Interactions of electroless catalysts with plasma-oxidized surfaces of polystyrene-based resins

Article abstract of DOI:10.1149/1.2096990

The way in which chemically modified polymer surfaces (substrates) affect the activity of electroless catalysts was examined. Surfaces of three injection-molded styrene containing polymers [polystyrene (PS), poly(styrene-acrylonitrile) (SAN), and poly(acrylonitrile-butadiene-styrene) (ABS)] were modified by either plasma oxidation or by plasma oxidation followed by immersion in sodium hydroxide solution. After modification, two palladium catalyst systems (a two-step palladium catalyst and a commercial colloid catalysts vary unpredictable and differently as the polymer, surface treatment, and electroless bath are changed. X-ray photoelectron spectroscopy results show only a weak correlation between surface composition and platability: (i) plasma-treated polymers show a net increase in surface oxygen, present mostly as carbonyl, (ii) immersing the plasma-exposed surfaces in alkaline solutions lowers oxygen and carbonyl concentrations. Some of these results differ from those previously obtained with photo-oxidized surfaces.
