Polystyrene and polyethyleneterephthalate surfaces were exposed to helium, oxygen/helium and nitrogen/hydrogen plasmas singly and in combination. The treated surfaces were evaluated by water contact‐angle measurements and by x‐ray photoelectron spectroscopy. It was found that the oxygen and nitrogen tend to graft to common carbon atoms, to form amide groups. The water wettability was found to correlate with the fraction of electronegative atoms incorporated into the surface. © 1998 John Wiley & Sons, Ltd.
