Abstract
A thermoplastic elastomer barrier layer is disclosed. The thermoplastic elastomer barrier layer may be grafted to a substrate for preventing contaminants from permeating through the substrate or for preventing contaminants, which may permeate through the substrate, from permeating beyond the substrate. The thermoplastic elastomer barrier layer is grafted to the substrate by a thermal grafting process.
