1. An ion selective electrode comprising:
- a poly(ethylene terephthalate) substrate having a major surface containing nitrogen;
a layer of a silver containing material deposited directly on said major surface of said substrate, selected areas of said silver layer comprising a silver halide, the remainder of said silver layer comprising silver metal areas and a layer of nickel metal selectively deposited over said silver metal areas.

Abstract
A method is disclosed for producing Ag/Ni composite ion selective electrode on polymer substrates. By utilizing a nitrogen glow discharge pretreatment of the polymer substrate, silver may be deposited directly thereon. Further, because of the glow discharge pretreatment, aging of the silver layer prior to nickel deposition and bleaching operation is not necessary.
