Abstract
A nitrile-containing material is bonded to the surface of a rubber substrate in order to increase the wettability of the surface. A rubber substrate is placed in the afterglow region of an electrodeless glow-discharge chamber. A nitrile-containing material such as an acrylonitrile monomer is introduced into the chamber, causing the monomer to polymerize and bond to the surface of the rubber substrate. In one embodiment, the surface of the rubber is etched with sulfuric acid prior to bonding the nitrile-containing material to the surface.
