Surface oxidation method using chlorine dioxide radical (ClO2•) for poly(phenylene sulfide) (PPS) was developed. During the oxidation reaction, sulfonyl groups and sulfite groups were successfully introduced to the surface of the PPS films. The water contact angle of the surface of the PPS film decreased dramatically after the oxidation, indicating that the surface hydrophilicity was improved. Electroless plating demonstrates that typical metals could be tightly deposited on the surface of oxidized PPS film and cannot be removed. This method provides an effective, clean, energy-saving treatment for super engineering plastics.
