Nonelectrolytic plating of nickel onto three types of polypropylene-homopolymer, random copolymer and block copolymer (with ethylene)-were investigated. The substrate plates were pretreated with ozone, and adhesion strength of the plated samples was tested and evaluated by the cross cut and thermal cycle methods The effects of ozone pretreatment on the properties of the plated samples were then discussed in terms of the chemical and morphological changes found in the polypropylene surfaces after treatment. Ozone treatment is shown to provide sufficient surface modification for plating, and sufficient adhesion strength is thougth to be obtained by the cooperation of polar interaction and the anchor effect between metal and substrate caused by the ozone etching It was also found that solvent washing after ozone treatment is important in obtaining better metal abhesion.
